VSS 2005 Clients Freeze

Hello

We have a Visual SourceSafe 2005 server and four clients running Visual
Studio 2005. They interface to the server using the plug-in to SourceSafe,
but they also have Visual SourceSafe Client 6.0 installed. Both clients and
server are running Windows XP Professional SP2.

The database size is 2.33GB.

Lately, a terrible phenomenon started which prevents our programmers from
working:
Whenever they perform Check In, Check Out or Get Latest their client freezes
for between 30 seconds to over 10 minutes.

We performed the following operations to counteract the problem:
1. We reinstalled the operating system to some of the programmers
2. We purchased a new server and moved the DB to it
3. We purchased new computers for the programmers we installed new systems for
4. We replaced the whole networking infrastructure to brand new Nortel
switches

Surprisingly, none of the above helped the situation at all.

We ran a network sniffing application (Microsoft Network Monitor 3.1) on one
of the clients and then on the server and found a very interesting thing:
The client freezes right after it sends a TCP SMB packet called "Rename
Request". It will stay frozen until it receives a TCP SMB reply from the
server called "Rename Response". As long as the client does not receive the
"Rename Response" packet from the server it will stay frozen, and that can be
between 30 seconds to well over 10 minutes (at which point we simply kill the
client).

As I said, this happens with fresh Windows installations and brand new
hardware.
This happens also when only one client connects to the server.

During the time the client is frozen the server reacts to every other
service it provides, and at incredible speed too. So this means that the
hardware as well as the network are perfect.

Any help will be greatly appreciated.

Thanks,
Erez.
