Well folks here is a good one for you!

I have 100 NT 4.0 Workstations and each of has been restricted using the Registry to limit them to 2 concurrent connections by my predecessor! I now need to return them, if necessary to their default of 10 concurrent connections. Does anyone know the registry key that my perdecessor used? Is there any tools out there I can use to simplify the task of changing them all?

I don't recall the key that controls this, but Microsoft has finally produced a tool to simplify the process. CConnect.exe is included in the Windows 2000 Resource kit; it allows you to adjust the number of connections for each client. Unfortunately, it has to be installed on each of your client machines. See the Knowledge Base at support.microsoft.com and reference article Q237282 for more information.

The knowledge base Article does not mention the number of Concurrent connections for a Workstation, only for users.

Well, this is just an idea to look at, can't say if it's right or not.

Every time a user connects to a computer accross the network they connect to the IPC$ share, along with what ever they are trying to connect to. In server manager look at thelist of shares, find the IPC$ share and look at it's properties. See if "User limit" is set to the Max or to Allow only two users.

hope that helps...

My predecessor introduced the concept of Client Server networking to a group of peer to peer users. To force them into using the Server a little, more he edited the Registries of all the Workstations to prevent the users from doing this.

Or try this:

Change,
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanManServer\Parameters\Users

from 0x00 to 0xFFFFFFFF.

I'm guessing it say 0x00, but change it to 0xFFFFFFFF nevertheless...

Do you have The Windows 2000 Resource Kit. There is a utility on it called CConnect.exe that should help you accomplish this. It works with 2000 and NT 4.0. Hope this helps.

You have several options for distributin gthe change, you can use SMS to deploy it, or you and remote control the machine and import the corrected key.

HKEY_LOCAL_MACHINE\System\CurrentControlSetServices\LANManServer\parameters\User

make your changes 0XFFFFFFF which returns to the default setting.

If the machines are close by I would take control as the Domain Admin and import the registry key. Next reboot would set it and they would have the default connections.

I don't know the exact registry key, but it is possible to update all of the keys at once with a program called 'Script Logic' that we have been using for several months and it works great. We have used it to update certain registry keys for over 200 PC's.

Just change the value in

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanManServer\Parameters\Users

to 0xFFFFFFFF

That's all, Eugen

Hi,

just change this Key:

-----------------------------------------------------------
Registry path:

HKEY_LOCAL_MACHINE\System
\CurrentControlSet
\Services
\LanmanServer
\Parameters

Users REG_DWORD 0x1?0xFFFFFFFE | 0xFFFFFFFF users

Default: 0xFFFFFFFF

Specifies the maximum number of users that are permitted
to log on to the Server service simultaneously.

Value Meaning
0x1 - 0xFFFFFFFE The maximum number of users who can be logged on simultaneously.

0xFFFFFFFF There is no limit to the number of users

who can be logged on simultaneously.

-----------------------------------------------------------------

Distribute the Reg.Patch with
User Manager Pro.

Mass changes to all NT/2000 workstations/servers users,
password,groups, policies, rights, & registry
