Today we received this message:

Dear Novell Partner
Your subscription does not expire until your PartnerNet contract expires. However, some of the software licenses that are included in your subscription are time-based and set to expire every year on January 15.

The following product licenses will expire on January 15:
BorderManager 3.7 and 3.8
Cluster Services 1.01 and 1.7 (for NetWare 6.5)
eDirectory 8.7/8.8
NFS 3 and 4.1
NSBS 5.1, 6.0 and 6.5
NetWare 5.1, 6.0 and 6.5

If you do not update the licenses for these products, you will not be able to use the products beyond January 15, 2010, regardless of your subscription's expiration date.
Now what kind of service is this? In three days your server will be out of service!
Besides I think it is wrong; I can't recall we reinstalled licenses a year ago.

I am not that familiar with NW and did not install our NSBS 6.50 server. So I went to ConsoleOne only to find out that no info about license expiration is to be found here.
Then I followed the advice here from AndersG:

However, launching NWAdmn32 (not NWAdmin32) reveals that our license's evaluation start is N/A.
So could someone please confirm that we have a perpetual license installed?
