microsoft windows box

When trying to perform a backup across peer to peer network from Windows 7 computer to the Windows XP computer you might get the following error:

Error code 0x81000039, remote share path not available

You should change the NTLM authentication level on Windows 7 machine:

Hit Start. Enter “gpedit.msc” in the Start Search box.
Navigate to: Computer Configuration | Windows Settings | Security Settings | Local Policies | Security Options
In the right pane, double-click on “Network security: LAN Manager authentication level” setting.
Change the level to “Send LM & NTLM – use NTLMv2 session security if negotiated”.

    This did not help my situation trying to back up a Win7 machine to a network server. I can access the path through my computer but the backups won’t run.
