I was not able to access a newly joined Windows 7 computer on our domain from our Windows 2000 Server. I just received that error. â€œCannot perform the requested operationâ€ Sharing was setup ok, permissions and security set ok, firewall was turned off. I saw an Event ID 2017 on the Windows 7 system, too. Something about â€œunable to allocate from the system nonpaged poolâ€.
I found this online. Add the MaxNonpagedMemoryUsage value below in the clientâ€™s registry. (Windows 7 system) Make a restore point first so you can undo if any problems arise.
DWORD VALUE: 0xFFFFFFFF
Next, restart the â€œServerâ€ service on the Windows 7 machine. Then go back to Windows 2000 Server and try to connect to \\window7machine and see if it can access it now.
This worked great for me, hopefully it works for you too. However, it may be wise to increase that value in small increments from the default, which I THINK is 0x100000. I just maxed it out and on my client system to test, and itâ€™s working fine. Just thought Iâ€™d make note of it. If you have further problems, or this doesnâ€™t fix the issue, remove the value and reboot. This should return it back to the default.
