I have one XP Media Center 2002 SP2 machine in my network that is giving me problems. We have two offices that the user travels between, and whenever the use is in office B, the machine will not obtain an IP address from, or get DNS service from the domain controller in that office. If I manually set the IP address and set the DNS server as the domain controller in office A (the two offices are connected via a PIX 501 VPN), it works fine. The user also brings the laptop home and uses it on his home network. All of the other computers in the office B are operating normally, but they all run XP Pro or Win2k Pro.
The other thing that I am concerned about is the fact that this machine is the only one in my network that uses AOL. I have the AOL firewall turned off, and have windows firewall configured through group policy for all computers in my domain.
There are also some issues related to the wireless network settings for this computer. The user normally uses the wired NIC to connect to my network, but there is also a WAP in the office. While I was troubleshooting the issue originally, I disabled the wireless adapter, but then reenabled it later. After reenabling it, I could not run ipconfig from the command prompt anymore, whereas before, I could. Whenever I would try to run ipconfig, I would get the following message:
An internal error occurred: the device does not recognize the command.
Please contact Microsoft Product Support Services for further help.
Additional information: Unable to retrieve WINS parameters.
I havent been able to find anything online about this error. I also tried to disable the wireless connection again, but the computer failed to respond.
This specific issue has developed only recently, but there have been issues on and off with this computer over time. Just nothing that I haven't been able to figure out.
