Network Delays

[Hinkhig]

Hi,

I have a strange problem, there are some long network delays when trying to

access network resources (shared directories & printers). It does not occur

all the time but randomly (they are getting more frequent).

I have 7 Windows 2003 servers in the environment and the problem appears to

be happening on any of them (although I only have 1 file and print server so

it is show most of the time on that one but shared resources I use on other

servers are also affected)

When I go to open a network directory the system freezes for up to 40 seconds

before displaying the list of files in the directory. I can see nothing

which is causing this but it is beginning to get annoying when users are

navigating to open files. Also when I print there are delays showing the

list of printers available.

Has anyone experienced a similar issue? Are there any tools I can use to

investigate what is causing this as I have no clue as to what is causing

this. I have captured the packets using etehreal but cannot see where there

are any problems, all I can see is excessive checksum errors but do not know

where to look to find out what is causing these.

Thanks

You may be able to safely ignore the checksum errors. WireShark (used to be Ethereal) doesn't see the checksum calculation if it takes place on the NIC instead of on the CPU as many NIC's now do, so it reports an error where there is none. Are you using Ethereal or WireShark? If you're using Ethereal, I'd uninstall it and update to WireShark.

Did you recently remove or re-name any network resources? Did you take a printer offline without removing it as a shared resource on a server for example?

Anything in the Application Logs, or any of the Event Logs?
