Ask Dr. Bob Your NT Questions

Q: We have many users sharing common apps and a single interface. Is there any way to copy user group information from one user to another?

You can use GRPTOREG.EXE and REGTOGRP.EXE from the Windows NT 3.5/3.51 Resource Kit. REGTOGRP.EXE creates a Windows NT .GRP file in the current directory for each of your Program Manager groups. GRPTOREG.EXE converts a .GRP file created by REGTOGRP and inserts the values into the Registry.

1. Make the appropriate changes to your desktop environment.
2. From the command line, type REGTOGRP.
3. Copy the .GRP files to the new user's directory.
4. From the command line, type GRP TOREG followed by the groupfiles. GRPTOREG will accept the parameters /o and /c where /o specifies that any existing Program Manager group with the same name should be overwritten and /c creates a Common group from the groupfile (otherwise, a Personal group is created). For the /c switch to work, you must be logged on as a member of the Administrators group. If you want to specify more than one file, separate filenames with spaces: for example, grptoreg /o /c c:\user\bob\bob.grp c:\user\bob\bob1.grp.

Q: In Windows for Workgroups, it's easy to eliminate a system maintaining a browser server list. How do you accomplish this in NT?

You can accomplish the same thing by adding the following information to your Registry (see screen 1).

1. Traverse the Registry tree until you come to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Browser\Parameters key.
2. Select Edit from the menu, and then select Add Value from the drop-down box.
3. For Value Name, type in: Maintain ServerList. For Data Type, select REG_SZ. For String Value, type No.
4. Reboot the system.

Q: I have heard that there are switches you can place in BOOT.INI to help with diagnostics and tuning. What are some of these switches?

The /MAXMEM=x switch in BOOT.INI controls how much physical dynamic RAM Windows NT will use when your computer starts (see screen 2). If you add /MAXMEM=12 to a BOOT.INI configuration description line, then your machine will act as if it has 12MB of physical RAM when you boot the computer using that configuration, regardless of amount of memory present.

The /SOS switch shows the loading of drivers one at a time so you can determine which driver is creating boot difficulty. In a multiprocessor machine, the /NUMPROCS=x switch allows you to set the number of processors the system will use.

Q: We received the following error in the Server Event Log :
Event ID: 2022
Source: srv
Detail: The server was unable to find a free connection 48 times in the last 60 seconds.
How can we fix this?

You have to use the Registry Editor to work around this problem (see screen 3).

1. Traverse the Registry tree until you come to HKEY_LOCAL_MACHINESYSTEM\CurrentControlSet\Services\LanmanServer\Parameters.
2. Select Edit, and then select Add Value and add the following values:
   Value Name: MaxFreeConnections
   Data Type: REG_DWORD
   Data: 8
   Value Name: MaxWorkItems
   Data Type: REG_DWORD
   Data: 255
3. From the command prompt, type NET CONFIG SERVER / AUTODISCONNECT:-1.
4. Reboot the system in order for the changes to take effect.
