Could not connect to Windows Vista share, error message Insufficient resources

This is a known issue with Windows XP, Windows Server 2000 and Windows Server 2003, but a number of users have reported that the solution explained here also fixes Windows Vista.

The installed value of the IRPStackSize parameter is often too small to allow additional network clients to connect to the Windows file sharing service.

Here are the instructions for making the change, but see the Microsoft article if you need more help.

  • Click Edit, point to New, and then click DWORD Value.
