File and printer sharing - clients disconnects randomly

File and print sharing stops working for some computers randomly on a 15 PCs network (internet café).
While ping works fine for both IP address and name, cannot connect to shared folder or printer.

After restarting computer with the shared folder and printer on, it’s starts working for a while before problem start happening again. (Restarting client doesn’t solve it, only server)
Cannot see any error or warning messages in system or application logs related to the time it’s happening on both server and client

Reinstalled OS on the server - no result
increased default TCPIP connection limit to 200- no result

Server dell PE CS 440 - XP pro sp3
9 clients - XP home SP3
5 clients - Windows 7
internet café management system - CafeSuite

If you patched tcpip.sys, you realize this is a violation of the Terms of Service, hence illegal, right?

You need a server. Thats the only legal way to accomplish this......

XP Pro is not designed to support more than 10 inbound connections.

to johnb6767:
well, I patched it just to understand the problem
but its still haven't sorted it
johnb6767Commented:
Regardless of why you patched it, its a violation of the EULA, to circumvent a feature to limit the amount of connections....

Kurt4949Commented:
"Using an EE question to help you circumvent that is not allowed here."

That's not what the author was asking.  From what I gather, the author did that to see if that was the issue before even posting the question.  Author should switch it back to the default\legal 10 connection limit and question should stay open to find answer to original issue...
AnvarUKAuthor Commented:
I'm in the process of testing Windows server 2003 to try to solve this issue
until then I cannot confirm the problem is solved
AnvarUKAuthor Commented:
to those worried, I restored original tcpip.sys as changing it did not help anyway
so the problem is still open
acl-puzzCommented:
if you want to avoid any limits then use Linux its free to everyone works great,fast,secure countless benifits... download Kubuntu or Fedora 12 desktop versions

and if you need to set them as a file server after downloading simply ask to us

and mention yours exact requirements

I know I posted this yesterday but some how it was deleted??


If the share your trying to access is on windows 7 then this might be the issue.

 Set the following registry key to ‘1':
HKLM\SYSTEM\CurrentControlSet\Control\Session  Manager\Memory  Management\LargeSystemCache

Set the  following registry key to ‘3':
HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size  

After making those changes restart the PC.
