OK, here is a really tough one, so I am going to assign alot of points on this one.
We have a Windows 2003 Development domain with 6 Windows 2003 Servers, several running standard edition and a couple running Web Edition. When we browse the network from one of the win2k3 servers to another win2k3 server, the shares of that server are displayed in approximately 2-3 seconds. No lag whatsoever! When we browse our production environment from a win2k3 server to a win2k server, only takes about2-3 seconds (no lag again). When we browse the network using one of our win2k production servers to the win2k3 development servers, there is also no lag, approximately 2-3 seconds.
Where we are having the issue is any win2k or winXP workstations! When the workstations browse the network to one of the win2k3 servers, there is a lag of approximately 15 seconds. This also occurs when we try to execute an application that looks at data on the development win2k3 servers. The network browsing for the production win2k machines are fine (2-3 seconds). This tells me there is an issue specifically from the workstation class machines to the win2k3 server class machines. It seems as almost a priority has been set between the servers and all other requests are denied.
Any thoughts on the matter would be great!
