I went ahead and uninstalled Terminal Server. After doing so I mapped to the network drive which has the application I am trying to execute (VC6). Again with no luck, I still receive the permission error. I went ahead and logged out of the account with permission issues and logged on with the account that works to delete the non-working account and re-add it again. This also did not work. Here is some more info on my network setup. Name - Server Type - Domain/Workgroup ------------------------------------------------ 1) BuildMachine - Windows 2003 server - workgroup 2) DevMachine - Windows 2003 server - workgroup 3) AdminMachine - Windows 2003 SBS - Domain Machine 1, BuildMachine, is the one which has the issues after installing Terminal Server. Machine 2, DevMachine, is almost exactly the same but has never had Terminal Server installed. All users on DevMachine are able to map to AdminMachine and execute applications without a problem. Only 2 users on BuildMachine (Default Administrator, and locally created Admin account before TS install) are able to connect. Since I uninstalled Terminal Server and still see the issue I am thinking that its a possibility some restricted policy had been enabled and was never disabled after uninstall. Uninstalling and installing of Terminal Server requires a reboot so everything should have been reset afterwards. However I have looked at all the policies in Local Computer Policy editor and nothing jumps out at me restricting this type of access. I also checked out the Group Policy Object editor as well. I will keep posting as I make progress. I am half tempted to reinstall the OS. We have a backup of the system, but I am not sure if it is a backup after installing TS or not. (if anyone reads devshed forums I have posted this there too)
