So I have a 2003 standard server running terminal server. After actvatation it ran well for 100 days as a trial period. Then i had to buy some CALs so that it could continue runing. I bought 6 packs of 5 retail device cals and installed them in the Terminal server licensing module. After installing those 30 CAL's people were able to connect again. Now in this module they were listed as Temporary Licenses for Windows Server 2003 - Terminal server per device cal token with the type temporary. It issues them as people log in and out and only allows 30 people in at any one time. I needed some more CAL's recently and i purchased 5 more from the same place. Now when I installed these retail device CAL's they showed up as Windows Server 2003 - Terminal Server Device CAL tokens but the type says Retail purchase total 5 issued 5. Now 35 people can log in at anyone time. Now when people are logging in the temporary licenses say they are about to expire. I did a little research online and it said that once these expire it will issue it one from the license pool if there are licenses available. I have tried to reinstall the original retail license packs to see if they would show up in as available licenses in the retail type. When i do this it says Error unable to vaildate the following codes because they are already activated. I am afraid that once these temporary licenses expire people wont be able to connect and it will not issues them a new license. If anyone has had a simliar experience or has any information on this subject please let me know. Thanks.
