Hi Paul and Mike

We are grateful for the responses.

I am post my existing winsock settings that I have acquired.
trace file created:
Type = 1 Buff = 4096 Prot = 4 Timeout = 20 Retries = 1
Successful socket initialization. WinSock version 1.1
Description: 'WinSock 2.0'
WINSOCK STATUS
System Status: 'Running'
The IP address 192.39.0.104 will be used for the host name 'CPNTA'
WinSock send and receive buffer sizes: 8192/8192
Socket connected successfully!

SCRIPT COMPLETED
Process_Command: Script Processing completed<00>

..... after the 1 hour some communication happens back anf forth ...

The last message from my client to server is the
printer has just been enabled
ATTN_KEEPALIVE (keepalive sent)

After which there is no response from server and after 22 seconds the client trace says
WINSOCK
Server closed data socket! WSAGETSELECTERROR msg param code = 10053
WINSOCK
Client socket closed!

Pardon my Ignorance
By Additional information you mean, I should use the getsockopt functions for getting those options and putting them down into my trace file am i right?

One more question : How will I get other settings like hardware card whether its gone to sleep, suspended etc ?

Adding trace file information hmm .. I WILL GET THIS INCLUDED In our next build. Thanks paul for that

Thanks for the registry information as well
I will ask them to export and send me the registry settings at
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services from both his Windows 2003 server as well as his windows XP machine.

Another interesting thing is that once he upgraded to windows 7 this problem got away.
Usually its the other way round for some of our customers LOL


To enumerate my present course of action Just in case it would help anyone who is in the same situation as I am in
What I can do right now to get the resolution is to create a simple exe that gets specific network information
E.g. here at
http://tangentsoft.net/wskfaq/examples/getifaces.html
... plus any information that i get as reply from this thread.

Ask the customer to execute the program before the issue and after this issue

Thanks in anticipation
