AD Domain Name and Internet Domain Name

Hello, I have recently taken over administration of an SBS2003 R2 network.
The installation was performed on new hardware during the Christmas holidays.
There are some major performance issues in that when user’s brows folders or
just try to access data on the server it is very slow. I am looking for a
reason for this poor performance. The hardware installed is more then
sufficient and they did not experience these issues with there old server so
cabling can not be an issue.

One item that has caught my attention is the fact that the active directory
domain name is now the same as there internet domain name. This was not the
case with there old server. They are running ISA server. Could this be my
problem and if so how do I fix it.

Thanks for your time.

Chris

I doubt this is related at all. The only real problem you face in a config
such as this is that, when a LAN-connected user wants to find a resource on
the public domain (such as a publicly-hosted website, etc.) they won't be
able to get to it unless you add the appropriate host entry in the
forward-lookup zone of the AD DNS to get them there - such as,

www ---> public IP adress of website

etc.

What I'd be curious about is:

* Antivirus software on server (realtime file-level AV should be set to
inbound/save only)
* ipconfig /all from server & a client
* network cards on server & clients locked down at a specific speed/duplex
setting, not using autosense
