Vince, Did you power your old PDC on being hooked up to the network or not? If you were plugged in you had 2 PDC on your network at a time. One of these 2 should became a PDC or your network is screwed. Check it in the Server Manager and demote your old PDC to BDC for sure. Check the Event Viewer on your exchange box for services that did not start as well to find the dependancy. Now I think you could demote your exchange to BDC pretty safely for a couple of reasons: 1. You can always promote it back if something does't work 2. Exchange 5.5 doesn't need to run on PDC. Moreover I don't think it is recommended. You have it like that only because of small Business Server. Hope this helps Pav -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx]On Behalf Of Vince Tan Sent: Wednesday, November 27, 2002 10:35 AM To: 'thin@xxxxxxxxxxxxx' Subject: [THIN] OT: NT4 Domain to W2k AD upgrade PART 2 (Exchange twist) Hello again, After getting all the advise (by the way, thanks to all), I decided to start my upgrade process. I installed 2 new BDC (machine b and c) to my NT4 domain, then shut down my PDC which is also my exchange server. I then promoted one of the new BDC (machine C) to a PDC, then took it off line and just stored it. The next step was promoting the other new BDC (machine B) to a PDC. Everything works so far. So I proceeding turning on my old PDC (the one with exchange running on it) thinking that I could get exchange running again and then demote the machine to a BDC. After it started, Exchange did not start at all. It gave me an Event ID 7001 error for all 5 exchange services. Event ID: 7001 Source: Service Control Manager Type: Error Description: The Microsoft Exchange Event Service service depends on the Microsoft Exchange Information Store service which failed to start because of the following error: The dependency service or group failed to start. Event ID: 7001 Source: Service Control Manager Type:Error Description: The Microsoft Exchange Message Transfer Agent service depends on the Microsoft Exchange Directory service which failed to start because of the following error: The dependency service or group failed to start. Event ID: 7001 Source: Service Control Manager Type: Error Description: The Microsoft Exchange Information Store service depends on the Microsoft Exchange Directory service which failed to start because of the following error: The dependency service or group failed to start. Event ID: 7001 Source: Service Control Manager Type:Error Description: The Microsoft Directory service depends on the Microsoft Exchange System Attendant service which failed to start because of the following error: The dependency service or group failed to start. Event ID: 7001 Source: Service Control Manager Type:Error Description: The Microsoft Exchange System Attendant service depends on the Netlogon service which failed to start because of the following error: The service have returned a service specific error code. I have not demoted this machine so there are 2 PDC. I am afraid to demote this because I can't really afford to have exchange down. Could having the 2 PDC be the cause of the exchange problem? Below was my original message. Thanks again and Happy Thanksgiving everyone. Vince From: Vince Tan [mailto:VinceT@xxxxxxxxxxxx] Sent: Tuesday, November 26, 2002 9:14 AM To: 'thin@xxxxxxxxxxxxx' Subject: [THIN] OT: NT4 Domain to W2k AD upgrade advise Hi everyone, I'm taking the leap to active directory finally so I'm trying to plan out what is the best strategy to approach this task. My network consist of only one NT4 domain, a PDC (NT4 Small Business Edition with Exchange) and a BDC (NT4 Server). I also have a few NT4 Servers and a couple of W2k servers running as member server. I also plan to upgrade my Exchange 5.5 to 2000. So here is what I am thinking of doing: 1. Because the PDC and BDC are both running in old HP LC3 boxes, I can not reuse them or upgrade them so I am going to get a couple of new boxes. 2. Plan to making one of the new box (machine A) a new BDC to the NT4 Domain 3. Promote the new BDC to a PDC 4. Upgrade this new PDC to Win2K DC 5. Install the 2nd new box (machine B) and make it a Win2K DC and sync with the other DC 6. Demote machine A from being a DC and then remove it from the network completely 7. Install fresh W2k server on machine A and make it a DC, then sync to machine B 8. Install exchange in machine A Is this the right approach? Do I need to take it off my production network while doing all the upgrade or can I just do the upgrade on my actual network since none of my existing server will be touched except for the old PDC which will have to be taken off line and demote to BDC Thanks for any advise Vince *********************************************** This Weeks Sponsor OneApp Total Control Control, Secure and Audit your Thin Client Systems http://www.oneapp.co.uk *********************************************** For Archives, to Unsubscribe, Subscribe or set Digest or Vacation mode use the below link. http://thethin.net/citrixlist.cfm *********************************************** This Weeks Sponsor OneApp Total Control Control, Secure and Audit your Thin Client Systems http://www.oneapp.co.uk *********************************************** For Archives, to Unsubscribe, Subscribe or set Digest or Vacation mode use the below link. http://thethin.net/citrixlist.cfm
