Re: IPsec tunnel and WIndows 2000 Terminal server
I think this is not an issue of IPsec.
Rather, this is obviously the Windows 2000 licensing question.
Windows 2000 once installed employs following algorithm (or a like)
to accept clients on it's terminal services:
- Sets the start of 90-days evaluation period
- When a client is requesting connection on terminal service,
the attempt is made to locate Terminal Service License Server on
- If failed, then just issue dummy certificate and accept connection.
- Once 90 days is over, server rejects any clients under above case.
The License Server can be found as additional Windows 2000 component
Once installed it uses similar approach but with respect of real license that
be requested from Microsoft within 90 days once License Server is installed.
While this (additional) evaluation period is not expired, the license server
temporary certificates (licenses) upon request, but sets the expiration date of
according to happened evaluation period.
After this, second 90-days, period is over your got to activate the license
requesting a license from Microsoft the way similar to one used by Sun
for its products.
