This is only an issue if you are using a computer that is not part of the domain (typically a VPC configured for workgroup).
People that use BizTalk tend to have a nice image that sports VS, BizTalk, SQL server, and Team Explorer if you use TFS. 9 times out of 10 this image is not part of the domain were the TFS server resides. This means that every single time you open visual studio you have to enter your domain credentials! This is tedious, boring and sometimes quite irritating. The reason is that you do not get that nice little tick box that says; “Remember my password”.
However there is a nice work around.
Open Team Explorer, right-click a project and choose “Show Project Portal”.
You will then get this nice dialog asking for your credentials.
There is that nice little tick box! Simply enter your credentials, tick the box and click OK.
Now you don’t have to enter you credentials again when opening Visual Studio.
Also, as pointed out by commenter Daniel Brünteson, you can easily add the credentials directly to the “Credential Manager”. This is a really nice way to handle credentials.
However, it is not a part of windows server 2003 or 2008, that tend to be the favoured operating systems when developing server side solutions. If you use Windows Vista (poor thing) or Windows 7 you can take full advantage of the credentials manager.
