Guru's, i encountered a very, very strange problem and i am looking for an explanation.
My customer is using a 2940 uplinked via fiber to a 3750 stack.
Clients are connected to the 2940 with 100 Mb/F, and a server is connected to the 3750 on 1000baseT.
A 10 MB file transfer from client to this server or vv takes 10 minutes. The same transfer to another server connected on the same 3750 takes seconds.
The server is a HP DL360 generation 5, Win2K3, sp2.
When we remove SP2 from the server, transfer takes seconds.
When we connect the client to a 2960 in the same network, (server on SP2) transfer takes seconds.
The problem seems to be in the combination HP with 2003/SP2 and a 2940.
We have tried several 2940 images. During a sniffing session the only strange thing i see is that the used window size is max; 65535.
Anyone ideas in this?
