SUMMARY
One of the following methods could be used when you are considering moving SNA Server from one Windows NT domain to another.



MORE INFORMATION
You can choose one of the methods below to help make a smooth transition. These steps will work as long as the Windows NT servers are Member Servers. If they are a primary domain controller (PDC) or backup domain controller (BDC) of the OLD domain, then Windows NT would need to be reinstalled as well as SNA Server.

Method 1

 * Remove all SNA Servers to be moved from the OLD domain through Server Manager (in Windows NT Administrative Tools).
 * Then add all SNA Servers to NEW domain through Server Manager under the Windows NT Administrative Tools.
 * Change all SNA-related services under the Control Panel Services tool to use the new user name and password that was created on the NEW domain for SNA Services to Log On As interactively.
 * Change the following three User Rights located on the Polices menu of User Manager on the NEW Windows NT domain:
 * Act as part of the operating system.
 * Generate security audits.
 * Log on as a service.

NOTE: For SNA Server 2.11, the services run under the Local System account, so this is not necessary.

- This new user account has to be added to the following groups:
 * If it is in a Windows NT domain, then add the account to the domain administrators group.
 * If it is a Windows NT Member Server, the account also needs to be added to the Local Administrators group.

Method 2
NOTE: This method can be used as long as you are not currently using or planning to use in the future any SNA service specifying a specific user account such as Host Security, SNA Print Server, Encryption, or any other account that may require one.
 * Remove all SNA Servers from the OLD domain through Server Manager (in Windows NT Administrative Tools).
 * Add all SNA Servers to the NEW domain through Server Manager (in Windows NT Administrative Tools).
 * Change all SNA-related services in the Control Panel Services tool to use the System Account to Log On As.

Method 3

 * Remove all SNA Servers from the OLD domain through Server Manager (in Windows NT Administrative Tools).
 * Add all SNA Servers to the NEW domain through Server Manager (in Windows NT Administrative Tools).
 * Copy the Com.cfg from \\System\Config\ to a safe location.
 * Remove SNA Server from all three servers.
 * Reinstall all SNA Servers one at a time, specifying the new user name and password.
 * Then copy back the Com.cfg file to the location specified above.
