I'd appreciate anybody's help for this matter: I'm trying to upgrade my WINDOWS NT 4.0 server to Windows 2003 server. In order to verify any possible problem, I executed the "winnt32" utility with "/checkupgradeonly" option But the following messages is issued: "Error reading information from netmap.inf from OEM directories pre-set by the administrator" I wonder what's wrong, why and how I could work out this issue. Thanks in advanced.

Thanks. We'll let you know when a new response is added.

Ok, there are a whole lot of issues with this upgrade. This upgrade path isn’t supported by Microsoft. Not only may there be hardware related issues, but in addition, you would have to upgrade to Windows 2000 Server first, then 2003. This is the smoothest path.

Ironically, I am finishing a final draft of an upgrade of an NT4 network to 2000 that may be of some help. I will be posting this on my Website at http://www.iis-resources.com in the coming week. If you wouldn’t mind shooting me a direct email, I will forward to you, in its rough format, so that you may get started in the next few days.

Cordially,

    AS per MS: Windows NT? 4.0 upgrade is supported by Service Pack 5 (SP5) or later. If earlier version of server pack is installed, the upgrade is not possible. Usefull link please read carefully all aspects of the upgrade. http://www.microsoft.com/technet/community/events/windows2003srv/tnt1-74.mspx

    Yes isn't that a 2003 R2 improvement? I know I have read the 2000 to 2003 path on MS site too. In any case back to the original question. The error reflects the default locations and file names of the version of 2003 running from the CD for installation with administrator credentials (administrator of the CD OS). One of three possibilities occurs to me. (1) You changed the standard NT4 folder structure by moving files or naming them different. Of particular suspicion C:WINNT. Look at documentation for the CD on how to change this path in your commandline inputs. Isn't netmap.inf a way to do this? (2) Netmap.inf file doesn't exist in the expected location. Again your paths aren't Microsoft defaults for NT4 == or you were supposed to create/copy NETMAP.INF to tell the check program what the file paths are. (3) Somehow the permissions to NETMAP.INF deny local administrator from full permissions. The 2003 CDs actually do read and enforce permissions placed on files and folders by the disk booted OS -- unlike NT4 where accounts of running OSes were never matched up to permissions of other installs.
