Question: I just installed Communicator on my Microsoft Windows NT system and now every time I log into my system, it opens up my C:\winnt.0\system32 directory. Why is it doing this?
Answer: This is a known issue with Microsoft Windows NT. It indicates a problem with your registry-- typically a corrupt or empty entry in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run or HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run.
For more details, read the article System32 Folder Opens When Logging into Windows NT on Microsoft's online support center at:
Or this one:
1. Edit: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer. If the right hand pane has an entry NoSaveSettings that is a 1, set it to zero until the problem is resolved. This should be a REG_BINARY value.
2. Edit: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
For each Value, make sure that the string is valid, i.e., if the Value is ActiveMovie File Extensions, the string of this REG_SZ entry should be ActMovie.exe /Check and not null. The string must always start with an executable file. If it doesn't, fix it or delete the Value.
