We have about 7 computers on a Windows domain with a Windows 2003 PDC. We recently upgraded the Windows 2003 PDC to Service Pack 1. All of the computers appear to be fine except one. They are all running wireless NICs to connect to the server through a Belkin Pre-N unit.
We at first thought something must have happened due to the server service pack update but soon discovered that that this was isolated and that when we changed NICs it helped out and it was able to get back on the domain. We finally splurged and bought an actual Pre-N NIC to go with the Pre-N router and signal strength is much better, we get a dhcp lease and consequently can use the Internet, yet the unit will not join the domain now. This has really got us baffled.
What could be going on here? We need this to work immediately as we are in a time critical situation.
