3 Major complaints - Computer Management missing properties tab explained in detail.
Please ignore this if you are already familiar with how it use to work.
In XP PRO it worked as follows:
Right click on Computer Management -take the Action- ->Connect to another computer
->Right click on "Computer Management" (at the top of the tree)
->Properties - Now missing
There were 2 tabs (Computer Name and Advanced)
In Computer Name you could change the "Computer Description"
In Advanced you had the same option as the Advanced Tab with XP's
system properties advanced tab.
The Advanced tab showed the "System properties advanced tab" which includes the following:
Performance <settings>
Environmental variables <settings>
startup and recovery <settings>
Vista and Windows 7 the last step(Properties) is missing from Computer Management period!

I hope this helps.
