Slow browsing .. changing DNS to 8.8.8.8 improves

Users are experiencing slow browsing issues, however when the DNS settings on the local workstation are forced to 8.8.8.8, browsing is better.

Default DNS setting is 192.168.0.150, which is the dns server.

This is because 8.8.8.8 is google DNS with quite a decent infrastructure and bandwidth.

Do you have forwarding setup for all non-internal domain names  ?
Scobber

actually, 8.8.8.8 wont be faster then local resolution.
it has nothing to do with bandwidth because you still need to use your congested pipe to get there.

Change your DNS server to strict RFC
click Properties on your DNS server in the DNS mmc snapin
goto Advanced
change name checking to Strict RFC (ANSI)

goto forwarders and delete all of them
goto root hints and delete all of them

click copy from server and enter 8.8.8.8

give that a go

Nothing has changed since yesterday when it was working, except the main router's firmware, which was updated.

make sure your main router has no DNS resolver running inside it.
and there is no forwarding to your servers DNS

what make/model router is it?
