Our company has a Windows Server 2003 R2 Standard Edition which now becomes unstable sometimes. So we would like to reinstall it.
This server is the only server in our company. It serves as DC, DNS server, file server & print server. It contains the AD and file data shared with the clients computers.
I want to know if the following steps are okay:
1. Backup the System State
2. Downgrade from DC to member server
3. Quit the domain
4. Reinstall the Windows
5. Upgrade to DC
6. Restore the AD from backup
7. Install other softwares
Please comment. Thank you very much.
