Cached password in Windows non-domain PCs

Windows stores passwords in a cache, that needs to be updated when your Windows domain (WIN) password is changed, and when the computer do not logon to the Windows domain.
If not changed, printing from computers *not* connected to the domain (WIN) will fail. This concerns network drives too.

1. Open the "Run.." box (Windows key + R key)
2. Paste this line into the Run box: rundll32.exe keymgr.dll, KRShowKeyMgr
3. Open Properties for the "win.dtu.dk" and/or "nas1.imm.dtu.dk" entry and retype your (new) password.
4. Click OKand say "no" to update password on the Domain.

This is tested on Windows XP, Vista and 7
