General Networking

I-286 Windows NT automatically disconnects idle sessions after a set number of minutes. To disable this feature (or at least set it to a ridiculously high number of minutes), use the following registry setting.

Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\Services\LanmanServer\ Parameters

Add the following value

Value Name: Autodisconnect
Data Type: REG_DWORD
Value: Oxffffffff

Restart the system for this value to take effect.

I-287 If you continually get the dreaded error 3013, “The redirector has timed out to Servername,” in your system log, fix this problem with this registry entry.

Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\Services\LanmanWorkstation\ Parameters

Increase the following value under the Parameters key or add it if it doesn’t already exist.

Value Name: SessTimeOut
Data Type: REG_DWORD
Value: 1

I-288 Your 3COM fast Ethernet card is hanging when you perform a soft reset, and the event log says something about bus mastering. This registry entry fixes your problem.

Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\Services\EL59X1\Parameters

Add the following value under the Parameters key.

Value Name: BusMaster
Data Type: REG_SZ
Value: no

This change disables bus mastering on the network card. Restart the machine for these changes to take effect.

I-289 If your Windows NT workstation maintains a browser list and you want to disable this feature, change this registry entry.

Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\Services\Browser\Parameters

Add the following value under the Parameters key.

Value Name: MaintainServerList
Data Type: REG_SZ
Value: no

I-290 Problem: You receive the following error repeatedly in the Server event log:

Event ID: 2022
Source: srv
Detail: The server was unable to find free connection xx times in the last xx seconds.

The actual number represented by xx varies depending on your circumstances. Changing this registry entry helps you work around the problem.

Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\Services\LanmanServer\ Parameters
1.  Add the following two values under the Parameters key.
Value Name: MaxFreeConnections
Data Type: REG_DWORD
Value: 8

Value Name: MaxWorkItems
Data Type: REG_DWORD
Value: 255
2.  Next, modify this registry parameter to turn off AutoDisconnect.
Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\Services\LanmanServer\ Parameters

Add the following value under the Parameters key:

Value Name: AutoDisconnect
Data Type: REG_DWORD
Value: FFFFFFFF

Reboot your system for these changes to take effect.

I-291 You’re trying to set up a connection to your ISP so that your workstation lets other computers on the network access the Internet. The problem is that you can see your machine but nothing else. Try this registry modification to solve the problem.

Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\Services\RASARP\Parameters

Add the following value under the Parameters key:

Value Name: DisableOtherSourcePackets
Data Type: REG_DWORD
Value: 0

I-292 Are you tired of your server flooding you with alert messages? You don’t want to turn them off; you just don’t want them sent as frequently. This registry entry lets you specify how often Windows NT checks alert conditions and sends appropriate messages.

Hive: HKEY_LOCAL_MACHINE
Key: System\CurrentControlSet\Services\LanmanServer\ Parameters

Add the following value:

Value Name: AlertSched
Data Type: REG_DWORD
Value: 5

Valid values are from 1 to 65,535, and they are in minutes. The default is 5 minutes. Restart your machine for these values to take effect.
