Fast traffic from server, but slow traffic to client
Posted on 2011-04-19
Hi, and thanks for any assist...
I have a client with strange network problem. In a simple client server setup (MS SBS 2003 and XP clients, and a simple 16 port DLink Gigabit switch and a patch bay sitting between all clients and the server. Only one client is experiencing application issues with a client-server application. When trying to reinstall this application from the server, it was taking abnormally long, so I finally tried to test connectivity between this client and the server. To test this, a transferred a 350mb file from the client to the share drive on the server, which was very fast (<6 minutes), but when transferring the same file back from the server to the client, it was estimated to take 3 hours.
No other performance issues with the affected client. Plenty of RAM, CPU's are not challenged
I tried three other clients with the same test, and all sent and received with excellent performance.
So, my questions are: does this sound like a NIC issue? Or something else? What can I do to staple down the root cause?
