IT has moved the location of the svn server to a different box. As a result all the source control paths need changed. I can't find where to do it in VS2010+AnkSvn. The change source control dialog (File-Subversion-Change Source Control) lists the SCC binding URL, but as a read-only value and doesn't appear to provide any way to change it.
I think it's the "Switch solution" button on the Pending Changes toolbar. Press it, enter the new URL and press OK.
Right click on project in VS, goto subversion and select 'switch project'. here you can change your svn server.
