Slow Internal Network since ISA 2004

[bernie321]

Hi

Does ISA 2004 monitor internal network communications, as since its install we have had slow internal network access and when rules are changed and saved there is a momentary disconnection of internal clients (e.g. open word docs crashing that are saved on the server).

Any advice would be much appreciated.

Make sure you have DNS setup correctly.

DNS Settings:

Configure the server NIC to only list itself or other DCs, no ISP DNS gets configured on the NIC TCP/IP properties.

In DHCP, set the DNS scope option to only provide the IP of your local DNS server

For any statically configured IPs, make sure the DNS only lists local DNS servers and not ISP DNS.

In the DNS snap-in on the forwarders tab enter your ISP DNS.

I hope you find this post helpful.

Regards,

Mark
