what platform are you runnign your patch deploy on? Go to the the commit portion inside show results of the job, right click on it and select undo. Alternatively you can right-click on the result of the job itself and click undo.
this didn't work in most cases for patches. In about SP4, the option was introduced for Windows 2003 patches and a recent SP may make it work for Win2k8. Some Unix OSes (e.g. RedHat) do not support patch uninstalls though.
Yes sorry forgot to mention that im running sp4. yes it works for w2k3 and w2k8 R2, w2k8 standard does not work yet. Unix OSes are trickier.
