Data transmission error?

[bofhrevenge2]

Can anyone give me some ideas how I can troubleshoot a network link.

We are running a Windows 2003 Active Directory and use group policy to distribute software. We have several blocks on site all linked with gig fibre and most of them work flawlessly allowing us to distribute software and send large pring jobs. One block experiences errors when we try to transfer any large amounts of data, we have about forty PC's in the block and they all fail at random when trying to install software. The same software installs perfectly on the PC's in the other blocks and they are all identical. There's also problems sending print jobs the HP 4100 will complain frequently of receiving corrupt data.
Users can however open Word docs and work happily as long as they don't try to transfer large amounts of data. If I try to copy a 100meg file from a server across the link Windows will say it cannot contact the server after a few meg, I can do this test easily in all the other blocks.

Can anyone suggest what could be causing these problems and where I should start to try and troubleshoot this?

We are using all Planet switches a mix of FGSW-2402 and FGSW-2403's and WGS3-404's for the backbone.

Thanks.

Check the speed/duplex settings. DO NOT rely on Autonegotiation to solve all the handshaking. Hard code the settings per port/unit.

Just my $.02

Ok i'll take a look on monday i'm pretty sure they are the same as the other links tho, if they arn't hard coded i'll set them.

Cheers.
