- TITLE :Promoting BDC to PDC Fails Using OS/2 Controllers w/ Slow CPUs
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:
-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system version 3.1
- - Microsoft Windows NT Advanced Server version 3.1
- --------------------------------------------------------------------
-
- SUMMARY
- =======
-
- Promoting a server to a domain controlling server in a pure OS/2
- domain (a domain with an OS/2 primary domain controller (PDC) and OS/2
- backup domain controllers (BDC) only) often fails if the OS/2
- computers are slower than 386/16 computers.
-
- RESOLUTION
- ==========
-
- Do not run Server Manager on OS/2 domains with really slow machines.
- Instead, use the tools provided with Microsoft LAN Manager 2.x for
- OS/2 to perform the promotion manually.
-

- ================
-
- Steps to Reproduce the Problem
- ------------------------------
-
- 1. Execute Server Manager focused on a pure OS/2 domain.
-
- 2. Select a BDC, and choose Promote from the Computer menu.
-
- After confirming the request, Server Manager starts the promotion
- process. This process involves a number of operations, including
- starting and stopping the NetLogon service on the selected machine
- and the PDC. The final operation in this sequence is to restart the
- NetLogon service on the old PDC (which is, by now, a BDC). This
- operation can time out if the OS/2 machines do not respond quickly
- enough (within about 45 seconds). If this problem occurs, you will
- see a message similar to the following:
-
- Could not start the NETLOGON service on \\<machine>.
- Error 2186: The service is not responding to the control
- function.
