Hi, At our DataCentre I have SQL server on the LAN side of the firewall and IIS server on the DMZ side. I have setup the rules to allow traffic from LAN 2 DMZ and 1433 from DMZ to LAN therein safeguarding the data should the IIS box get breached. I decided to backup the SQL files to the IIS box using NTBACKUP, didnt work so tried normal xcopy batch files again didnt work. However they do work when I run them manually, ie run the batch file from a command prompt or NTBACKUP direct from its console, its only when they are scheduled via task scheduler or NTBACKUPs own scheduler that problems occur with no real indictaion why. For example if I run "xcopy D:\mydb.bak \\remoteserver\bakupfolder\" it works great. If I schedule this using task scheduler it fails to run. I have tried running using system account on SQL & IIS, creasting an identical account on each box and running that way, still no joy! SQL box is Server 2000 SP4 & IIS box is Server 2003 SP2.. ANy ideas appreciated..
