Windows 7 and Windows 8: allow storing credentials for remote machines

Start local group policy editor, Start – Run (Win+R) – gpedit.msc
Go to Local Computer Policy –> Computer Configuration –> Administrative Templates –> System –> Credentials Delegation
Edit “Allow delegating saved credentials”
Enable the policy, click Show and enter the value “TERMSRV/*” into the list (TERMSRV shouldn’t be changed, leave it).

Do the same thing for the following policies:

• “Allow delegating saved credentials”
• “Allow delegating saved credentials with NTLM-only server authentication”

Close the policy editor, open a command prompt and use “gpupdate /force” to apply the policy directly.
