Virtual File Server Disappears after a few hours

hi everyone,

not sure if should go here or in file server forum.

we migrated our network shares virtual (hyper-v) file server.
and randomly after few hours server disappears.
(can not access start->run-> \\servername)

however, can still ping server, , remote desktop it.

all event logs clean, both on parent server , virtual file server.

to fix, restart virtual file server, nothing else.
but shares/server disappear anywhere little 2 hours as 12.

this brand new dell poweredge 2950-iii 16gb ram , 2 quad-core xeon 2.33 cpus.

the parent server running win2008 standard 64bit,
and running hyper-v roll, nothing else.

the file server running win2008 standard 64bit,
and running file server roll dfs (though no replication partners yet) publish share ad.

the other software installed on 2 machines symantec endpoint protection 11.
and using anti-virus feature (network intrusion, etc... disabled.

it did not make difference when trying access via \\servername\sharename or \\domainname.com\sharename.

any appreciated, old server coming out of lease , needs go soon.

thanks,
chris

hi,

 

even network intrusion feature disabled on both systems, suggest disable symantec endpoint protection 11 there known issue between symantec endpoint protection 11  , windows server.

 

windows servers stop accepting network connections symantec endpoint protection 11.0 installed

http://service1.symantec.com/support/ent-security.nsf/docid/2007102613484948

 

windows server 2008 network shares become unresponsive symantec endpoint protection 11 or symantec antivirus 10.2 client installed , auto-protect enabled

if issue continues, please create share folder on parent os , try visit client. fqdn , ip address. please let me know detailed error message.

 

at same time, suggest try analyze detailed network packages when trying visit file server. please download , install microsoft network monitor 3.2 on server.

close other programs , stop other activities on both servers. start network monitor, click new capture, click start button, please try test. when "time out" appears, click stop. click save button, save cap file , compress it. send zip file tfwst@microsoft.com research.

 

thanks.
