Need help sorting things out, dealing with cached credentials, Outlook 2010, and network settings.
Posted on 2013-01-15
My place of work has two separate buildings and both are setup with domain controllers. One via wireless networking and the other wired. Both domains are named the same.
My boss had been using a pc with Mark's user profile on the wired network. She then brought it over to the other building (that uses wireless networking) and was able to access and send email via Outlook 2010 using Mark's profile (probably via cached credentials). It was NOT set to login to the wireless networking domain controller yet.
Life was happy until I decided to add this computer to the wireless domain. Since I am somewhat new to setting up networking settings, I couldn't add the pc to the wireless initially and tried a few different things. (I had all sorts of messages about Trust Relationships, and DNS Server not found..) etc. One thing I tried was changing the computer name, MARK02-PC to MARK02PC. I also tried to Reset the Computer in AD User/Computer, also Deleted the Computer from list of Domain Computers and added it back while inside AD User/Computer. Also tried leaving and re-entering the domain.
Eventually, after trial and error I changed the computer name back to the original MARK02-PC and was able to get it logged into the wireless domain. (I pointed the wireless adapter to the IP address of the DNS server).
The bad thing now is my boss can no longer login to the Mark user profile (cached credentials erased?) I am hoping to take it back over to the building with the wired network, login as Mark and regain the credentials. Will this work? I hope so, Mark user account has very important emails.
I hope my changing of the computer name had no effect on the SID?
