Map network drive gets disconnected

[hpsait]

I have an external HDD connected to a Windows 2008 server which I share in a domain environment. I can map a drive successfully to that external hard drive, but it gets removed after reboot.

I would suspect group policy as the cause. gpresult might reveal the source of the problem

The problem is that all my other map network drives shows up every time, except for this mapping to an external drive.

What about this Group Policy?

The policy "Always wait for the network at computer startup and logon" is found:

In my case the map network drive gets removed completely. No Red X. We are not running any login scripts.

Does the event log say anything?

Might have something to do with it being an external drive, is it USB? It may be going to sleep,low power mode, and when the other machines boot up, they just don't see it.

 

[hpsait]

Nothing is the logs.Yes it is USB.

I need to have the USB drive connected to a server in order to do Backup Exec backups.

Any feedback from anyone how to fix this?

Do these mentioned Registry locations exist (in Windows 7) and look correct, and are the access permissions suitable?

More feedback. The external hard drive is a WD My Book. I have also tried a different external HDD without any luck. The USB WD drive is connected to a HP Proliant server running Windows 2008 Server. I have also tried a different server.
We have a mix of Windows XP and 7 users and this happens to all of them. I have also updated the WD drivers on the server and have checked the power settings on the server. If I go Start - Run and use the UNC name the share comes up and I can map a drive, but as soon as the users reboot their device Windows drops the map drive.
I'm looking at the previous post for more details, but I dont believe it is a user setting (Windows).
