My saved credentials do not work.

If your computer is part of a domain, by default you are not allowed to save your credentials when you connect to a remote computer. But you can change this.

Note: You must be logged on as an administrator to perform these steps.

  1. From the Windows Vista default Start menu, in the Start Search box, type: gpedit.msc. Press the ENTER key.

  2. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

  3. Under Computer Configuration, double-click Administrative Templates, double-click System, and then double-click Credentials Delegation.

  4. In the right pane, double-click Allow Saved Credentials with NTLM-only Server Authentication.

  5. In the dialog box that appears, click Enabled, and then click Show.

  6. In the Show Contents dialog box, click Add, type the name of the remote computer (server) in this format: TERMSRV\<computername>, and then click OK.

Note: Be sure to capitalize "TERMSRV" as shown. <computername> can either be the name of a specific remote computer (for example, TERMSRV/myremotepc) or you can use an asterisk (*) to include a group of computers (for example, TERMSRV/* or TERMSRV/*.corp.com). <computername> should exactly match the name you enter in the Computer box in Remote Desktop to connect to that remote computer.
