hi

first of appologies if not exchange issue hyper v issue/networking.

we have hyper v infrastructure virtual exchange 2010 ( 1 x cas/hub 1 x mailbox) , on past few weeks our cas server seems stop responding network.

you cannot ping the server or remote on it. way access via hyper v manager. when log on via hyper v manager seems ok. network there , can ping self not ping out other servers in domain ( either via name or ip address).

the way have got around restart server , starts working perfectly.

having through event viewer errors see around time goes down are.

dns client 1014 - name resolution name dns server timed out after none of configured dns servers responded.

i guess because nothing can contact server , server cannot contact other system

any ideas on how troubleshoot this.

this server happens in whole virtual environment

 

also side issue exchange have link mac address of network card. concidering shutting server down. removing network cards , re appying them , setting ip addresses again

 

many help
