Dell Optiplex 390 - Other Computers Cannot Access Machine Over The Network
Jul 25, 2012
I'm on a large network in my office and we recieved new computers(dell optiplex 390) I'm trying to access a mysqlexpress database on my machine from another one and I'm not able to even access the computer using \MYCOMPUTER method with the same user/pass as my machine on the one I'm trying to connect from. But still no one in my office can reach my computer.
My av is OfficeScan.
+ Disabling the firewall(windows no other firewall in place).
+ Checking network settings
+ enabling sharing settings
+ allowing anonymous connections via the regestry value
Very soon for the second time we will be replacing systems in our (grad school) student computer Lab from the time of its opening in January, 1998. The monitors are recessed down below glass desk surfaces and are 17-inch CRT (Dell).Our current (medium) computers are SFF GX-150 and have 512MB RAM (doubled from the original 256) and 80 GB hard drives. The new GX620 will have 2GB RAM, 160MB hard drive.In addition, our current 10/100 Ethernet LAN for this part of the campus is also supposed to be upgraded to Gigabit (switch). Any experience of using Gigabit in an organization's local area network to find out any concerns for which I should be alert as we begin this new phase. Incoming students arrive before middle of August so the switch-out needs to be done fairly quickly and smoothly. What concerns should I have?
I have a strange error on my home network that I cannot find a solution to.I have an Huawei SmartAX MT882 from TalkTalk acting as a modem connected to a D-Link DSL-G624T acting as a router/switch. Connected to the D-Link I have a Windows 7 Pro machine (64-bit, SP1) and an XP (home i think) machine (sp 2 i think).The SmartAX modem is set up to perform DHCP and DNS relaying and the D-Link has DHCP turned off and DNS relay turned off.The Win7 machine can access the network, get an IP address and access the internet without problems, regardless as to the status of the XP machine.The XP machine can access the network, get an IP address and access the internet with no problems ONLY of the win7 is powered up. When the win7 machine is off, the XP machine seems to drop about 25% of the ping packets between it and the D-Link router and has no internet access (because of this i assume). [code]
New Win-7 machine set up. I used the printer set-up wizard to install a networked printer in the new machine with absolutely no problem. Proved it would print from that machine.Now, I get a call informing me that her old XP machine, which had been printing to the network printer with no problems, will no longer print.Documents go into the print queue, but they don't get printed.No error messages show up.I did some messing around via remote access, and finally removed the printer with the intention of reinstalling it.Scanning for network printers turned up several redundant instances of the same printer with different names. Some are identified as "invalid" some a "access denied". Bottom line. I can't get any of the selections to install.On the Win-7 machine I did find a window that indicated that the printer is designated as being shared, but I didn't explicitly set it for sharing when I installed it. Also, I somehow got to a window that told me that for printers that were to be shared with other versions of windows I could optionally install drivers to support such machines. Didn't have the driver disk handy and took the window down. Now I can't even find it again.I need sorting this all out.Part of the problem is that out there in "network land" there are redundant remnants of previous installations that are being remembered inappropriately.
I did a clean install of Windows 7 32-bit on a Dell Optiplex 980. I don't know what driver is for the ethernet controller. Will you tell me? I just downloaded the INTEL_825XX-GIGABIT-PLATFORM_A06_R290983.exe (5MB). I don't know if this is it. I will try on Monday. Should I update the chipset driver too? What is the driver for that. I downloaded Intel_AMT-HECI_A05_R304259.exe (10MB). Is that right for the chipset?
I have a Dell Optiplex 780 running Windows XP and a wireless router model 7500 from Verizon. I recently bought this desktop and want to use my old one so the kids can play games on it. However I can't connect to the internet with the old system. I tried running a USB cable from the wireless modem to the old system to no avail. I tried hooking up a wireless-G Broadband router by Linksys to the wireless router and that didn't work. Does there have to be some wifi hardware/software on these desktops? [code]
Im unable to get my router working as my machine has no ethernet controllers installer.I have a dell, optiplex gx260. The lan in enabled in the Bios. I have searched and tried a number of driver None of which have worked, I have tried the 3com 3c905c txm, intel gigabit LOM, and im about to try the Intel 8254x1000 intregrated netwk driver (which i dont think'll work as its the same as the Lom one). if that doesnt work is it best to reinstall the chipset drivers?
Recently I got a brand new E1200 to replace Apple Extreme Base station for my home wireless network. The router deployed just fine except one weird problem. While all devices (desktops, laptops, cell phones, iPad) can access the router, one desktop (Dell Optiplex DX280) cannot see the router at all. The router network, even with default SSID, does not even show in the wireless network list, no matter how many times the list is refreshed. The wireless adapter (Dell TrueMobile 1300 USB2.0) is fine, since it picks up the router SSID when connected to another desktop. The stubborn desktop works just fine with previous Apple router and can see many networks around, like neighbors' networks. Thinking that some other previously installed software interferes with seeing the router SSID, I completely wiped and reformatted HD and reinstalled fresh copy of WinXP - still the same result, the desktop works just fine with the Apple router, but still cannot see E1200 SSID. The router was reset to factory defaults and all access restrictions were removed. While all the devices see the default SSID and can conncet to the router with no problems, the stubborn desktop keep completely ignoring it.
Again, every single component - desktop (Optiplex DX280), wireless USB adapter (TrueMobile 1800 USB2.0), routers (both Apple and Cisco) are functioning normally otherwise. It is the combination of Optiplex GX280 - TrueMobile 1300 - Cisco E1200 that does not work.
I recently installed VMplayer on my Win 7 machine, and I installed Win XP on the VM. So far everything seems to work fine. However, on my home network I have a Linksys NSLU2 mini network server which has a flash drive plugged in that contains my files that I access from any of my home PC's. No problem accessing it from the Win 7 machine, but when I try to setup a "new network place" on the XP system, I get an error telling me that the address is not valid.
I installed a fresh Windows XP Pro on my Optiplex gx270 last week. Everything was fine but now I cannot get an internet connection. I followed all the steps on the dell support web site for the windows reinstall, putting all the drivers on in the correct order, all from my original resource CD. Then downloaded the new recommended driver for my service tag from the dell site, and still no ethernet controller driver is found (a yellow question mark with an exclamation mark on top in windows device manager). Tried a couple of times with the dell online chat, but was disconnected right away. Then spent another 1+ hour on the phone with dell tech support this morning. After uninstalling and reinstalling the same drivers I had previously installed, they apparently had no other suggestions and disconnected me. So I'm left with what was a pretty decent machine that is incapable of connecting to the internet.
I recently purchase a refurbished Optiplex GX620 with WXP Professional OS. The ethernet controller, along with number of devices, needs a driver. I have downloaded what I think are the approprite files but get the message that the unzipped file is part of a series of disks and I need to insert the last of this series of disks. I ain't got no stinking disks!
I am taking a camera class, everyone sits a desk with a fairly new Optiplex 780, with Windows 7 pro on them and 20 inch Dell Professional monitors.I want to be able to setup something easily so the teacher can share his screen on all of the computers in the class, the projector is terrible.Net Meeting does not exist. Vista had Windows MeetingSpace which would have been absolutely perfect. Windows 7 has SharedView, which is discontinued, is a separate download, and has to be used over the internet with a windows live login.Is there some VNC, free app out there that the teacher can put on his laptop, and have everyone connect to? Over the lan? There are many web-based options, but that probably be slow.
I can use the Bomgar and work and host a presentation, which is what I will probably do, but I have a feeling it is going to suck up a ton of bandwidth and run like crap. We want to display examples of photography in full color.He of course doesn't even know of these plans. But I want to utilize these computers we are sitting at.Could I bring in a Vista laptop, start a MeetingSpace, and have the Windows 7 computers connect to it?
I see a lot of postings about getting the GX270 working with a ghost boot floppy.
Dell Optiplex GX270 Onboard Intel LOM (Intel 1000 Pro) and Ghost 8.0 Corporate Edition using a Ghost Console Boot Partition.I'm using identical Intel Drivers on both the floppy and the Boot Partition.It works from the floppy(only using PC-DOS however).
When started from the ghost console boot partition it pauses after displaying the MAC address of the card which after a few minutes it displays an error message "command interpreter missing (command.com)".
I've gotten the scenario to work with a Broadcom Gigabit Extreme network card, haven't tried this with an Intel Pro 1000 NIC (as opposed to the onboard NIC) to eliminate the driver as the culprit. I suspect this might have something to do with the SATA configuration.and no, the -FNI or the -NOIDE switch will not work in this situation as the *.exe that starts on the boot partition is ngctdos.exe and not ghost.exe.Which, I'm assuming is the app that listens for instructions from the Ghost Console.
I am wanting to move an existing wireless LAN PCI 802.11 b/g adapter WN5301A card from another tower computer into my Optiplex 755 mintower. Is this compatible, or do I need to get a different wireless card?
I have an ASUS RTN66U running Tomato firmware.I have temporary (a month or so) Internet access via a Huawei E3131 3G USB dongle. I am posting this question using said Internet access.
I would like other machines on my network to be able to access the Internet in the usual fashion. That is, through my ASUS router.My initial thought was to plug the dongle into the router and configure it to connect. However, it seems tomato does not support my dongle because I get a message to that effect in the log.
So my next thought was to "point" my router at my Windows machine which has the dongle plugged into it. Thus, any machine connecting to the router would then route through my Windows machine to the Internet.
As an example, I have 3 computers on a home network:
Machine A Machine B Machine C
What I would like to do is isolate "Machine C", so that it cannot communicate with "A" or "B" and vice versa. It should be an entirely separate entity.
Let's say I'm using a Linksys E4200. Is there a good way to configure the above scenario with the default firmware? Is it possible with non-default firmware such as DD-WRT or Tomato? I do not have experience with this but have no problem learning.
My understanding is that this can be done by placing "Machine C" in the DMZ. Unfortunately, I am told a lot of home routers do not have a secure way of setting up DMZ by default. The two routers solution can work but still requires restricting administrative access from "Machine C" and adds an additional potential point of failure.
My daughter bought a Dell Optiplex 745c from a company who is replacing their cmputers. This particdular computer does not have any drivers loaded for the installed NIC card, so te machine will not talk to the intenet. Are the drivers in the 745 and the 755 the same?
