Small Business Server 2011 SP1 Slow Network Performace
Posted on 2012-04-04
I have been dealing with a performance issue on our SBS2011 server since I inherited it 6 weeks ago. Users are reporting and I have verified that when accessing a file on the server, say a pdf (30K), the file takes over 30 secs to open. I have read alot about about IPv6 issues and TDI driver bug but all references say this should have been fixed in SP1 which is installed.
I looked in the netword card configuration and noticed under IPv6 that the IP address is set to automatic but the DNS is set to manual with an entry of "::1". Not sure that that is so if anyone has any idea please let me know.
Also, I noticed that the dns.exe service is using 600MB of memory consistently. With slow network performance could a dns configuration issue be the problem?
Any help would be appreciated.
