Link: Win7 forgets my file sharing credentials

My home network is based around Windows 7. Shocking, yes, I know -- but Win7 media center has a much better 10 foot interface than FrontRow and I can build each HTPC for around $300.... as compared to $600 for a MacMini which isn't expandable.

In any case, my Win7 machines were having a problem forgetting their login credentials for file sharing. Found the fix here: http://social.technet.microsoft.com/Forums/en-US/w7itpronetworking/thread/ef9b42b2-5695-4ac4-8aea-745aa532b981
