Duplicate Network Logon Connections - Win XP

[RicReeves]

I have a XP pro machine running as a server for 6 users who need to access the same database based application.

I know xp pro can handle 10 concurrent network connections so i didn't think this would be an issue.

However after some connection problems I noted in Computer Management->Shared Folders->Sessions that each user was logging on twice, once under the computers name and then a second time under the computers IP address. = 12 connections needed & therefore problems.

The [Computer Name] connection seems to be the Application logging onto the server and the [IP #] connection occours when users access data from the database.

Does anyone have any suggestions on how i can rectify this problem? Do you think its a problem within the software? (I've tried updating the hosts and lmhosts files hoping to link the two connections but no joy from either)

Any help is greatly appreciated!

Is the IP address of your "server" coded into the database client on the client machines somehow? Or is there a script running that maps a different path just for the database?

XP does not count connections the way you are.
If I map three shares and two printers, I still only have one conection to that share server.

Bcastner I agree with what you're saying but XP is definately logging on the computers twice once as the Name and again as the IP address, which is clogging up the available connections.

I know it should be only one connection per machine but this is not the case in this instance.

On other servers we have, running the same program (same version)in different offices, this time with one running Windows Server2k & 2 with Win2k that each of the computers connect only once as the computer name, not the IP address.

So i still think its something to do with how XP is treating the connections differently.

 

[bcastner]

It is recording the UNC map, it is not a different (in the important sense) a second connection.

I honestly feel you have other issues with your LAN.

Explore in detail, snakefoot's site, particularly issues with 100 mbs connections,

I rarely link this site, not because it is not great stuff, it is; but one can seriously screw things up if you try all the suggestions. Less is more.

I understand that but that doesn't fit the logic of my problem. Or does it?

If it does, then i suppose my question should be why is the XP machine only allowing 4/5 connections, when it should be 10?

 

[bcastner]

It is not a connection limit issue. Or should not be. Post you logon script here.

 

[RicReeves]

The networks are running as workgroups not as a domain. Is there still a logon script in this case? Where would it be on the XP machine?

Would it be helpful to compare this to the logon script on the working 2k machines?

 

[RicReeves]

Also I have noticed in the 'Sessions' window that the client PC's are connecting as guests but on the 2k machines they're not. Could this be a factor?

With regard to the KB Article i guess this is my problem:

The only way system A will have multiple sessions to another system, system Z, is if system A is running services that create logical connections to system Z. For example, if a user is logged on to system A as guest and a service is running on system A under the user1 account, and both the user and the service (as user1) establish connections to system Z, two sessions are established. Each logon session that uses the Server service counts against the connection limit.

Do you think i should therefore talk to my software people about whether the system is doing this?

It would be interesting to find out why it doesn't do this on the 2k machines tho. It must log the sessions differently.

Just as a reference:

The sessions file on the XP machine reads like this:
