So, you have Microsoft SQL Server 2005 Management Studio (SSMS) and when trying to connect “Server name” drop down list is filled with sensitive data:
To clear this list, all you have to do is delete this file:
C:\Documents and Settings\<user>\Application Data\Microsoft\Microsoft SQL Server\90\Tools\Shell\mru.dat.
Just remember, once you delete that file all of your previous connections will be lost. So make sure that you have any necessary IP addresses, usernames, and passwords that you’ll need to reconnect to your favorite/most used SQL Servers.
