Windows Storage Server 2003 SP2 - Insufficent system resources

Running into a problem trying to copy files 150GB to 300GB from a Windows

Storage Server 2003 SP2 to a server running Windows Server 2003 R2 SP2 . The

file will begin to copy and then I will get a message saying that, "Cannot

copy filename: Insufficient system resources exist to complete the requested

service." If I try to copy the file again, it appears to stop at the same

place each time. If I go to the other server and attempt to copy from the

storage server, then I get a message that there is no drive space on the

storage server, yet there is plenty of space available. If I reboot the

Windows Server and attempt the copy from either direction, it will still stop

at the same place. If I reboot the storage server, then it may or may not

allow me to copy the file. I have read and applied the knowledge base

article regarding the IRPStackSize registry change and it hasn't made a

difference. I saw a previous post on this same issue, but didn't see that it

solved the problem. There is very little information regarding Windows

Storage Server out on the net. Thoughts would be greatly appreciated.
