Repair Windows Server 2003

[cedillof]

I have a problem with win server 2003.

This is was happened:

I restart windows server because sap systems (dev and qos in the same server) were too slow. After it never started again, stayed in windows intialize fase. The the hw technician diagnostic that the raid mirroring wasnt synchronized and for this reason some windows files were corrupted. So we are now repairing the windows server via the installation cd option. Has anyone pass with this scenario, how it affect to sap system?

The situation is this.

The drive C with the OS is corrupted I will reinstall windows server 2003 (Local HDs)

Drive D is the Sap usr\sap folder

Drive E is the Database Files (SQL Server 2000)

Drive D and E are in good conditions (on eva disk array)

How can I reinstall sap service in windows server 2003 using the drive D (sap files folder usr/sap) and E (sap database)??

My sap version is SAP R/3 Enterprise Core 4.7 SR1 Extension Set 1.10

Hello Franklin,

I don't think that this will work if you don't have a backup of the system.

If you really have to re-install Windows 2003 from scratch you will have a "clean" system. So there will be no needed sap-users, no sap-registry keys in the registry, no entries in the services-file, no environment settings will be set and so on - all the things which are created while installing.

So I think without a backup of your system (or perhaps the c-drive) it is impossible to rebuild the SAP system - sorry.

Regards

easiest thing is to install SAP with installation CD, install:

central instance

upgrade kernel

SQL server

sp_attach

good luck.

What I did to repair sap.

1. Reinstall Server2003

2. Instal SQL Server (with sap sql server cd, otherwise you have to change collation to bin2)

3. Install Sap Central Instant ONLY.

Choose same drive for usr/sap folder

Choose same SID

4. Copy the usr/sap folder from the backup into the new folder.

5. Attach de DB to sql server

6. At SQL server: Create new login user dev and assign it to the db dev user

7. Assign login users to domain user DOMAIN\devadm with the following query

EXEC sp_change_users_login 'Update_One', 'dev', 'dev'

8. Assign login user to domain group DOMAIN\SAP_DEV_GlobalAdmin

9. Then the system start again 😃 but the transport system was down. =(

10. Make the domain group DOMAIN\Sap_<PRD/QoS_SID>_GlobalAdmin member of the local group SAP_LocalAdmin.

11. All set up back to work again. 😃

What do you want to know?

you MUST repair Windows before attempting to start SAP.

Without a valid OS, SAP is useless or will work bad.
