If you think you are safe in upgrading your patches for your server(win2k), think again. I have just returned from our Mandaue campus, I was installing Lotus Notes r5(for teachers evaluation and ranking) and for some reasons I'm having hard time connecting to our server at our main campus. Changing my connection and location settings, but still it was no good, I can't think of any reason why I won't be able to connect to our server, and even copied the system configuration of the other workstations that has lotus notes application. Then I've decided to go back to our main office to check what was really going on. While we were driving I've realized that two weeks ago I've downloaded and intalled a new hotfix(patch so to speak) to our server. But hey this is an update , this should be good for my machine. Hesitant at first if I will remove and uninstall the patch, but I did unintall it. Then after a cool reboot, and open my internet explorer and now able to connect to our mail server. At last.

The point is, check that hotfix, patch, upgrade whatever you call it, if it's compatible to your platform or application before releasing that to your system. I have nothing against those who are particular about these patches but be sure to check it and have a back up or you should be responsible to what ever upgrades you have installed to your system.
