The workstations have McAfee Enterprise 8.0i and Windows Defender. SP2
firewall is in place with the RDP protocol allowed for our central
office subnets and local subnet. During testing, we have disabled all
three. I have also tried connecting from workstation at the central
site that I moved outside the ISA firewall to ensure that wasn't
interfering.
I can connect to the machine, though, so basic connectivity issues are
not involved. The problem appears when trying to logon.
Testing yesterday seems to confirm that Autologon is at the root of the
problem; if it is turned off, the problem goes away. The stickler, of
course, is that I don't have the problem locally!
I am going to try Remoe Assistance today. This would be less useful
for troubleshooting, as it requires a remote presence, but....
