Security Update on Windows 2003 ver build 3718

I have the following pb : server restart unplanned. I
expected the follwing happen
MS03-039: A Buffer Overrun in RPCSS Could Allow an
Attacker to Run Malicious Programsto
I tried to fix the pb by installing the patch but i get
the error message :
Setup has detected that the build version of the system is
not Build 3790
The version of my system is an evaluation version Build
3718.
Do you have any idea to resolve this issue ?
Thanks

You should not still be running an evaluation version. They expire when
the product ships. That is why your update fails.
