Hi everyone;

We have 9 users using 1 cable modem connection the cable modem is hooked to a cisco switch and a home run to each computer.  5 of the computers are new dell's XP-Pro 2.4 ghz.-  1 is a HP XP-Pro1.5ghz.-  1 is a Gateway Win 2000 pro Pentium III and the other 2 computer are win 98se pentium III's.  Most times not all users are accessing the internet at the same time.
The networking and file sharing and printer sharing between the computers are great no problems at all.

The problem is the XP-Pro's drop or loose the connection to the internet and the operator has to "repair the Connection".  Sometimes the operator may go for hours and not loose the connection, other times the connection may drop 3-4 times in an hour. It has never happened that all XP's drop their internet connection at the same time.
   
Equipment includes Cisco Catalyst 2950 switch, Cisco 806 router, Prolog(Penteladata) cable connection 400 up/down, static IP address.

Any suggestions for a fix would be appreciated I am not the sharpest pencil when it comes to this kind of a problem.

thanks
Chet Ricewick(IT Dept)

Is this happening on all the XP's including the HP..??   From what I can see, I doubt if it has anything to do with your switch.  

Perhaps it has to do with the AutoDisconnect feature of XP...  (doubtful, but it is a shot..)

http://www.winguides.com/registry/display.php/194/

Change LAN Auto-disconnect Timeout (Windows NT/2000/XP):

Windows can be configured to automatically disconnect idle LAN sessions.  These are a set number of minutes.

Open your registry and find the key below.  Modify the value, or create a new string value, called 'Autodisconnect' and set it to equal the time in minutes before a session is disconnected.

Restart Windows for the change to take effect.

(Note: Set the value to 0xffffffff to disable the disconnection function.)

  (Default) REG_SZ (value not set)  
  Autodisconnect REG_DWORD 0xffffffff (4294967295)  
 
HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer
 
Registry Settings:
System Key: [HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\
Parameters]
Value Name: Autodisconnect
Data Type: REG_DWORD (DWORD Value)
Value Data: 0 to 4,294,967,295 (0xffffffff) in minutes
 
Disclaimer: Modifying the registry can cause serious problems that may require you to reinstall your operating system. We cannot guarantee that problems resulting from modifications to the registry can be solved. Use the information provided at your own risk.

In answer to your question Yes on the HP also.
I have gone in to the registery and checked the Value Data:you suggested and found it to be   "f" and behind that was (15) which I think would mean it was set to autodisconnect in 15 Min. of no use which makes sense to me.
I have changed the value on my HP and will see it it makes a difference.
My gut says it will.
Just hang fast for a little and we will see what happens.
Is this OK with you?

Thanks again

Chet

I just had this same issue with a Windows XP Home edition macjhine.  Hopefully this fix will fix the issue, as it is a really odd one.
