Hi, I'm running Plesk 7.5.4 on a brand new Windows 2003 Web Edition server and have encountered this problem 3 times, and each time I have had to re-image the server to make Plesk usable again. The problem is this: If I add a new domain name which resolves to another IP Address, Plesk displays a warning message and continues to register the domain. From this point on, every new domain I add are inaccessible and any domains I try to remove cannot be deleted and return an error. Something fundamental in the process breaks. From my trouble-shooting it seems that registering the new domain which already resolves to another IP is the root cause of the problem. An example error message by Plesk: "Unable to remove domains: Problems occured while removing domains: Unable to turn the domain OFF: domainmng failed: Run-time error: Execute usermng access off failed: Unhandled exception." I have applied all of the patches and hot fixes for Plesk - does not fix the issue. I have performed a Plesk Check & Repair - does not fix the issue. I have used the Plesk binary to restore all domain settings: C:\Program Files\SWsoft\Plesk\admin\bin>websrvmng.exe --reconfigure-all Nothing works! This is a fundamental problem - can anyone help?
