I have created 7+ new servers using the NW 6.5 SP7 DVD and upgraded 10
NW 6.5 SP5+ servers. I have an Access database that compares all the
NLMs on the server to each other. My question is, why do some of the
NLMs have different version numbers or different dates?

Shouldn't all the servers have the same NLM version and date?

For example, the DS version of an Upgraded server is v20216.5. Where
as the DS version of a newly created server is v20216.51.
