Can't Log On To Domain After Joining Workgroup
Jun 9, 2011
I cannot join domain it saying that "Computer name changes", A domain controller for the domain MyDomain could not be contacted.”. We have domain and workgroup, Actually first its already joined the domain, but I want to map the sharedrive inside the workgroup but I cannot map. Then I change to join workgroup. After I boot up I cannot log in with that user, I log in with administrator and the user is dissappear in the "User Account", but the profile inside document and setting still left surprise. I don't know why Now I create one more user, it can map to share drive also share folder. also can see all other network computer. But only left one is I cannot join the domain. I need this one because of we don't let our user using as administrator account. Before I testing this one I should backup, but now the time

I've just installed two ACS 5.2 appliances and I'm trying to get them to join my domain, I've setup an account that has the relevant permissions (tested the account on a laptop and it can join the machine to the domain).
The ACS keeps coming back with an invalid credentials to join the domain error despite the fact that I know the user in question has the correct permissions.
I have a suspicion that the problem is related to how the ACS handles the Active Directory Domain, we have a large domain that spans several domain controllers. The DNS server uses round robin DNS to serve a different DC's IP each time, however a typical windows laptop is aware of what controllers it's allowed to use whereas the ACS box doesn't appear to be.
The ACS servers are located in a network in the UK that is only allowed to talk to 2/6 DC's and I have no way of controlling what IP appears when the ACS tries to join the domain due to the round robin DNS.
Is there any way to get around this? Or any way to hard code a specific DC for the server to connect to? Even being able to add the DNS manually to a hosts file would work.

I have been having some issues with an ACS express joining a domain. This device previously had joined and after a weekend we received a notice that users were not authenticating to the domain. This in turn let us to find out the the device was unable to join the domain. Further research led us to find that the account the device was using to join the domain had been disabled. However, after re-enabling the account we would only recieve domain timeouts when tried to join. I opened a case with cisco and we have tried everything under the sun to no avail. I can ping the AD server (name & ip) from the ACS express. Cisco apply a root patch that allowed us to create hosts file entries on the device. I checked the system time and made sure it was within 5 minutes of the Domain controller time. In the logs of the ACS express the only thing I can really find is:
-"Checking remote join status: SMB connectivity failed"
-"Timeout reached in getting AD Diag info"
"acsxp/server Warning Server 0 is DisconnectedMode, IOException for reason, ipc socket connect; No such file or directory:
Recently we re-imaged the ACS and tried to join the domain without the old config on it and just received the same error. I reloaded the backup after that which also resulted in no change. I am starting to think that there is more of a domain issue rather than networking but am having issues finding a way to prove this via the logs. The are other ACS's configured in the network and the settings on this device match the settings on the other device in the network which are working correctly.

We have a computer running Windows 2000 Pro that used to connect to a domain at work. Upon bootup, it asks for the user/password.Yesterday we tried to connect it to a little home network by changing the domain to a workgroup with a different name (network name that i used at home) as well. Now when it boots up, asks for a user/password, but now it does not recognize my user name and password.I can log in as an administrator to the Workgroup with the new name. but i cannot access the old Domain with its user and passwords. I tried to change back to the old name and to domain, but when doing that i get and error messsage which says: The following error occurred validating the name "xxxxxxx" (network name that I use at home) this condition may be caused by a DNS lookup problem. so I'm not sure if a should run the clear DNS cache. and if in doing that I'll be able to restored it back to the stage that i was before I made the changes.

To start off, I work for a small business where we do not have an IT department
One of our users changed his domain to a workgroup (made us rethink who has admin access on all our PC's) thinking that it would somehow fix the problem he was having with not being able to print anything to a network printer. Well, this promptly called for a restart and upon restarting would not allow him to log back into the user account.
This all makes sense to me as to why it will not let him log-in using credentials that he is no longer a part of due to security restrictions. But my question is how do i recover the account? In other words, how do I go about rejoining that user account to the domain that everyone is located on.
If all new user accounts are defaulted to join the domain, how come its not just as easy to move a user from a workgroup back to that domain?
Also, the machine is running Windows XP. It's critical that I get the old user account set back up because it was used for Outlook e-mail as well as several important documents/spreadsheets. I know that none of these files are lost as I can still navigate to them through the Local Disk. But really I would like to get the old user account working instead of having to copy/paste all the old content to a new user account in order to hopefully retain all old settings and configurations. tl;dr A user on our domain moved his user account to a workgroup and now is unable to login or access his user account. How do I move the user account back to the domain?

I have a former corporate PC that logged into a domain server. Under <Control Panel><System> I changed from Domain to Workgroup. I now can't log on to any account including the administrator.I don't have the recovery disk. MS suggests a parallel installation of XP to provide access to the files on the disk. I can do that with any Linux CD. I don't have any data I want to recover. That was all stripped off before I got the PC. I do want to keep all the applications. If I reinstall XP, I will loose all the applications. I now know I can only logon to the administrator account if the PC is connected to the domain server. If I can restore the domain name, I can log on to the PC again.Where is the domain / group info kept and in what format?Is there a way of using a Linux CD to manually edit the XP files to restore / add a domain??

I am trying to join a Cisco Catalyst 3560X-24T-L to an existing VTP domain, my question is what configurations should I do to this switch?I have already gave it a hostname, setup passwords, enabled telnet, created a management address on port g0/24.I would like it to be on VLAN 13, is this done from my server switch, or done on the new switch?

I have a home computer which part of the home's workgroup and I have a office laptop which is part of a domain. Both of these are connected to the home wireless router and I can ping from one to the other via IP only and not by hostname. I have to access DB which is on my home computer (workgroup) from office laptop(domain). How do I achieve this? I search the internet and found we can enable sharing by IP. But my usecase will require access to the workgroup computer using hostname from laptop.

I am new to dealing with domain setups and Windows Server. Here is my setup:
Comcast business cable modem
Gigabit Switch
IBM x3100 M4 w/Xeon E3 1230, 16GB ECC DDR3 RAM Running SBS 2011 Standard
Custom PC with Win7 Pro, i7 3770, 12GB DDR3 RAM
What I would like to do is setup sbs 2011 as the domain controller and have the custom pc on that domain.Comcast business cable modem/router is set for defaults, handing out dhcp.
Both Server and custom pc are hooked into the switch which is hooked into the comcast router.SBS 2011 I believe I set it up with the default settings. Updated it so all the patches are on it. It sees the comcast router and connects to the internet no problem.
Custom PC is sees the comcast router no problem and gets its ip address from there like normal.When trying to join the domain on the sbs computer the custom computer cannot find it even though I can ping the server.

There are a total of 25 Cisco 3502 APs installed. 24 APs were discovered except for 1 AP. I run SH CDP NE on the switch and the AP was discovered by the switch but it does not have an IP address. On the output of the SH CDP NE DE, I noticed that on the AP that is not joining, the Platform is "cisco AIR-SAP3502E-E-K9" while the APs that joined the WLC, the Platform is "cisco AIR-CAP3502E-E-K9". The software versions are also different but this could be because the WLC already upgraded the IOS when the APs joined.Why is the Platform "SAP3502E" for the AP that did not join.

I had problems joining a 1131AG AP to a "new" 5508 WLC with 7.4.100.0 running. This AP has been connected to a, for me unknown controller for years. Now the customer wants to move this AP to a newer 5508 controller with 7.4.100.0 We [URL] could not get this AP to the controller connected. Now I have this AP on my desk. I have a 5508 (7.4.100.0) as well. I connected the AP to the same network as the WLC Management -> AP did not connect, tried to download the "new" IOS but didn't seem to work, same as already in the old tread. So I tried to login to the AP, but it seemed to have a for me unknown Account / Password.
-> I did a reset of the AP by pressing the mode button (about 2-3 sec.) during Power on (not connected to the network). Now I could log on to the AP. I deleted six crashinfos and connected the AP back to the network.
Now the AP joined the controller.
Does a "unknown" Password prevent the AP to join to a other WLC?
The AP hat 15740928 bytes total (6409728 bytes free) space on the Flash: was this enough for the new image? 15740928 bytes total (7798272 bytes free) after deleting the crashinfos
The customer has more AP's that has to join the new controller, would be nice that we don't have to reset all APs.

recently migrated APs from a 4400 to 5508 which had the 7.4 code and encountered an issue that I haven't see before, in short the APs would never join the 5508 even when the selction rules said it should.The AP would get a discovery response from both controllers and even though the 4400 had 98 APs attached and the 5508 just 1 and a factory reset was made on the AP, it would always join the 4400.
A packet capture showed that the first CAPWAP address from the 5508 was always an IPv6 whilst the 4400 always sent IPv4 CAPWAP control adressess, disabling the global IPv6 option on the 5508 ensured that the the first CAPWAP control address was now an IPv4 and the AP then happily joined the controller, IPv6 addresses were still showing up in the discovery responses but since it was no longer the first one in the packet the AP didn't mind.

It seems to start downloading the software. after a while it stops with the bolded output, twice the same Bytecount!?

info regarding my LAP521 access points that are refusing to join the WLC4402-12.This is my first lightweight access point implementation and I have 3 LAP521's and 1 AIR-CAP3502I-E-K9 access points on my network.They are meant to pick up ip address from external dhcp server and then join the WLC but only the 3502i joins successfuly while the 521's get dhcp address but do not join the WLC. From the logs, I can see that the WLC is discovered by the 521's and even get a response message from the controller but they are still unable to join as shown in the screenshot below.My WLC is running software version 7.0.230.0 and the 521's are running an lwapp image version 4.2.61.8.

I am trying to join my 1130AG-E-K9 AP to my 2016 WLC, but it is stuck in a boot loop and will not connect to the controller. [code] I found some details here: url... but I'm not sure what it means that I have a 'SSC AP'. I am not local to this AP, though I do have a console connection to it-what do I need to do to get it working again? It just continually goes through this error and reboots every 30 seconds or so, so it's useless at the moment.

I am performing a new install of a WLC 5760 and 3602i APs. I have limited experience in setting up WLCs. I am hitting a brick wall in getting the AP to join my WLC. My primary document has been this deployment guide:url...I have also sifted through many of the relevant portions of these guides: url...
I went through the setup wizard and followed the instructions in Ch. 2 to the letter (or at least I think I did). I have DHCP options 43 and 60 configured per the 3600 series Getting Started Guide.I believe my AP discovery process is sound because I see activity when I power on the AP and perform debug capwap ap all from the WLC. I have highlighted lines that I think are relevant. I have attempted to find the answer on my own by searching the Internet for these phrases. [code]

From the 3602i

I should note that 3500 APs are able to join this controller. The field guy is going to try to add the MAC address to the filter list when he gets back out on site to see if it allows it to join.
