This article details the steps I took to configure a Maintenance Window in the Symantec Management Platform (SMP) 7.1. These steps worked flawlessly for me, but should be reviewed with your architect first to ensure they will work for your environment. Some steps may be modified based on your requirements, so please keep that in mind when reading through this article.
2. Create Maintenance Window
2.1. Click Settings | Agents/Plug-ins | All Agent/Plug-ins.
2.2. Click Agents/Plug-ins | Symantec Management Agent | Settings | Maintenance Windows.
2.3. Clone the All Managed Computers policy.
Note: I, as well as the general public, agree that it is best to clone the out-of-the-box policies for ANYTHING and to rename and modify them to suite your needs.
2.4. Name it CSS Maintenance Window (or whatever name you want to make it applicable to your environment.)
2.4.1.Set Start to 10:00 a.m. and End to 7:45 a.m. (or whatever name you want to make it applicable to your environment.)
Note: This 'window' is the timeframe for which all activities are 'allowed' to take place. Since we only want to ensure that no activity takes place when the users first arrive for work until their first coffee break, we only want to keep all activity quiet from 7:45 am to 10:00 am.
2.4.2.Set Repeat to Week and choose M, T, W, U, F (or whatever days you like.)
2.4.3.Click Apply To and choose Computers.
2.4.4.Click Add rule and set it to exclude computers not in Group ATS Managed Assets (or whatever computers are applicable in your environment).
2.4.5.Click update results then click OK.
2.4.6.Click Save Changes.
2.4.7.Enable the policy.
2.5. For more specific detail, their are quite a few good KB's out there:
