If anybody is having problems backing up to network shares and gets the following error message: "Not enough server storage is available to process this command" Here's a solution: On the computer that the share is on, open the registry editor by going to Start>Run and typing in regedit and then ENTER. Edit the following: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters\IRPStackSize If "IRPStackSize" doesn't exist, right click, New>DWORD Set the value to 50, make sure the base is decimal. Then reboot your computer. Here's the Microsoft KB article http://support.microsoft.com/default.aspx?scid=kb;en-us;177078 I had a problem accessing shares that were connected to an external USB hard drive. Might be related to installing Norton Anti-Virus. I'm running Windows XP BTW.
