My problem is that the media servers actually hang or reboot themselves
 
This is symantec supports suggestion so far:
As regards to the case and the servers rebooting, my assumption here is that 
you have a 3rd party Windows program that is rebooting the server when there is 
a service stopped or TCP connect failure.   Check ALL the services on the 
Windows servers and make sure that NONE have the Recovery tab setting for 
"Restart the computer"

Bob,   I had the syndrome of device manager doing down on my W2K3 media servers 
when I took the master down or rebooted the master and it ?went away? when I 
updated to MP5. I see you are at MP4. Regards.

 Thats ALOT of SAN/ MEDIA Servers!! 70 !
I see it on 2 SAN Media Servers, but only when the NetBackup MASTER server 
Services are down or if the Server is restarted.
 
Once it comes back up, its fine!

Subject: [Veritas-bu] W2K3 media servers rebooting 
NB 5.1 MP4 
SSO with only master server as scan host
SL8500 firmware 3.02b
SL Console firmware 2.29.00
ACSLS 7.1.0
STK 9940B tape drives 1.35.409
tape device driver is Veritas 5.1.1.1 
(NetBackupTapeDeviceDriverInstall20060215_282214.exe)
RSM is DISABLED on the window servers
 
We have had some problems with W2003 servers rebooting when the NetBackup 
master server is shutdown and tape drives are taken offline.
 
Event log entry before reboot:
Cannot register shared drives for host mediaserver7 on host master1: cannot 
connect to vmd
 
 
Is this due to the master server being the only scan host?
We placed the entry SSO_SCAN_ABILITY = 0 in all media server vm.conf files 
except the master server.
BTW: we have 70 media/SAN media servers!
