SQL 2005 on Windows Server 2008 - Slow Connection Time

[GatorDBA]

Hey Folks,

Experiencing strange problem with SQL 2005 running on Windows Server
2008. When trying to connect via named pipes or tcp, it takes 25-45
seconds for the connection to be established. Looked at some posts
about IPv6 possibly causing the problem when in stacked ipv4/ipv6
environment, but not seeing any results after un-binding ipv6
protocol.

After running some tests, interaction with the DB Server is slow even
after connection. Queries against the same databases take longer on
this server versus an existing server.

Any ideas out there?

Thanks...

Do you connect with Windows authentication or SQL Server authentication?
If the former, could you try the latter and see if it makes any
difference?

Does this happen also when you run queries locally and you are connected
through shared memory?
