Ok here is my situation.
3 PC's all running Windows 7 Ultimate
1 Desktop connection via wire to router
2 Laptops connected via Wireless (Linksys wrg54g)
All 3 PC's are visible on all 3 PC's via the Homegroup in Windows Explorer. I can browse/copy/write files on all 3. All sweet. All 3 can print to the 2 Printers connected to the Desktop.
Laptop A is configured to Backup using the Windows 7 Backup to the Desktop. This works fine.
Laptop B however when trying to backup to the desktop I get an error message after I have selected the Drive in the setup screen and I've entered my username/password credentials
The error code is 0x80070043
I've tried everything and I'm quite experienced.
Both laptops for all intents and purposes are identical.
Any help would be greatly appreciated.
