Here is my environment:
10.1.1.x - Servers and support subnet (including DC and DNS)
10.1.2.x - Desktops
10.1.3.x - Desktops
All subnets uses 24bit netmask.
When I'm trying to join a XP client to the domain, I got the following message: "cannot perform the requested operation".
I checked IP configurations and everything looks fine.
The thing is: When I plug the same client machine in the 10.1.1.x subnet, I'm able to join it to the domain.
Things to consider:
1- My domain FQDN is only MI. Not mi.com or mi.local... Only MI. Is this a problem?!
2- DC is running Windows Server 2000 SP4. I have 3 DCs running...
3- XP client have SP2 and all patches available installed.
