We have a Win 2K3 Server DC, running Trend IMSS and Officescan. These both have web based management consoles hosted using IIS.
We wanted to take a look at Microsoft WSUS so installed it on this server, since we did this everytime we try to access the Trend management consoles or the default website we get:-
HTTP Error 401.1 - Unauthorized: Access is denied due to invalid credentials.
Internet Information Services (IIS)
I have uninstalled WSUS and we still get the same error.
