I have several networks that I work on that have all diplayed this problem. I have several shares on a win2000 member server that are mapped on win98 pcs. When the pcs boot in the morning the drives are fine but after serveral hours the connection is dropped. I can access the shares from the run command and the client/server application can still access infomation from the server. I can either reboot the pcs or disconnect and remap the drives but thats a real pain. This is limited to win98 pcs as most of the pcs are either win2000pro or xp.

any suggestions would help

There are several client attached to DNS have win98 OS and some clints have win2000 pro OS and some clints have winXP pro as wall as XP home. All users are divided in some group using group policies.

My problem is

some time users are not able to access their map network drive and error DNS unable to interpet format, Event code : 5774.
When I restart Server clients start accessing MAP network drive .

Y_Rawat, please post your question in a new thread.

rwbliss1783, regarding your question, here's a link that might help: http://support.microsoft.com/default.aspx?scid=kb;en-us;297684&Product=win2000.

Extracting the relavant info:

Cause:

This behavior occurs because Windows NT Server 4.0, Windows 2000 Server, and Windows Server 2003 can drop idle connections after a specified time-out period (by default, 15 minutes) to prevent wasting server resources on unused sessions. The connection can be re-established very quickly, if required.

Resolution:

Registry Editor
NOTE: You cannot use this method to turn off the autodisconnect feature of the Server service. You can only use this method to change the default time-out period for the autodisconnect feature. WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

Use Registry Editor to increase the default time-out period. To do this, follow these steps, and then quit Registry Editor:
Click Start, click Run, type regedit (Windows 2000 or Windows Server 2003) or type regedt32 (Windows NT 4.0), and then click OK.
Locate and then click the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters

In the right pane, click the autodisconnect value, and then on the Edit menu, click Modify. If the autodisconnect value does not exist, follow these steps:
On the Edit menu, point to New, and then click REG_DWORD.
Type autodisconnect, and then press ENTER.
Click Hexadecimal.
In the Value data box, type ffffffff, and then click OK.

Command Line
NOTE: If you use this method, you may turn off the autotuning feature for the Server service.

To change the default time-out period for the autodisconnect feature of the Server service, open a command prompt, type the following line, and then press ENTER
net config server /autodisconnect:number

where number is the number of minutes that you want the server to wait before it disconnects a mapped network drive. The maximum value for this command is 65,535.

NOTE: If you set the autodisconnect value to 0 (zero), the autodisconnect feature is not turned off, and the Server service disconnects mapped network drives after only a few seconds of idle time.

To turn off the autodisconnect feature, open a command prompt, type the following line, and then press ENTER:
net config server /autodisconnect:-1

I dont think this is a session timeout problem because win2000 amd xp clients do not disconnect at all. I did find a hotfix in article q278588 and have applied it to one pc. I'm going wait for a week or two and see if that corrects the problem

Dropped connections from Win98 clients in W2k surroundings might be name resolution problems; Win98 relies on WINS for name resolution. The usual questions:
Do you have a WINS server running, and is NetBIOS over TCP/IP enabled on your servers?

mapledrums,
the article number is probably 278558.

The article number is 278558 sorry about the error. The drives are mapped with the ip address so name resolution is not the problem.

I applied he knowledge base solution suggested by Y_Rawat and had my client track if it helped. Contacted her Friday because I hadn't heard from her ( not a bad thing ) and she said she had no reports of problems.

Many thanks to all who offered suggestions

It seems to me that Y_Rawat had posted a question instead of a solution (unless I'm reading it wrong).

Well, if you've had the problem solved yourself, you can post a request here http://www.experts-exchange.com/Community_Support/ to PAQ this question & refund your points, or accept the relavant comments, if there're any. Thanks.
