|I always run the cmd console and TFS IDE as administrator.|
The issue is resolved to an extent.
I normally connect to my client machines via VPN. When I am connected in that, it generates a dynamic IP. To check that, I used all the computer references as LocalHost/MachineName/MachineName.DomainName/DynamicIP/IP that is listed as IPV4. When I ran the PsExec from TFS, all the references failed other than the IP that is listed as IPV4.
For now it is okay, but still not sure why other references failed.
