Plesk Login prompt error

Plesk Login prompt Issue

A strange login prompt is presented when trying to view a website on a windows plesk account , even though the website directory is not password protected.

The Fix:
This issue results from the anonymous account password used to deliver the site to public web viewers , getting out of sync with the main account password. To fix, just re sync anonymous password by issuing the following command in the run dialog:

"%plesk_bin%\websrvmng.exe " --update-anon-password --domain-name=yourdomain.com
