Can't copy files larger than ~5MB from Windows Server 2008 to Windows Server 2003 over VPN.
Posted on 2009-05-05
Hi everyone... so I'm at my wits end now...
I have two sites connected VPN.
Site A has a Windows Server 2008 file server on it which has backups via xcopy copied to it from a PC which is on the LAN also on Site A.
Site B has a Windows Server 2003 file server that is SUPPOSED to have files copied via xcopy to it from Site A's Windows Server 2008 machine.
After upgrading Site A from Server 2003 to Server 2008 - I no longer can do my backups from Site A to Site B.
I have searched for solutions to this problem and have found various things to try. Thus far I have tried changing the MTU, disabling OpLocks, disabling SMB2.0 and various other things.
I also attempted to copy files to another Windows Server 2003 machine on Site A from the Windows Server 20008 server and had no problem copying it. In each instance of testing the copy I am copying the same folder. For instance... I have a folder we will call "Folder of Stuff" - when I copy "Folder of Stuff" from the Windows Server 2008 machine to the Windows Server 2003 which is also on Site A - the files copy over without a problem. When I try to copy "Folder of Stuff" from the Windows Server 2008 server on site A to the Windows Server 2003 server on Site B - the problems begin.
Errors I have gotten in event logs - it appears each time it fails to write the files over I am getting an error or mrxsmb event id 50. I have also searched that and can't seem to find anything.
Any help would be much appreciated - I'm on the brink of just going back to Windows Server 2003 all together.
