Network management software

Interesting, because we are going through the same thing.
It pretty much depends upon how big your budget it. We are looking at unicenter TNG by Ca and Openview by HP. There are some smaller stuff, like Netreo, which will give it to ya in a box.
For client Management, I like Altiris. They have a combination where you can do everything from push/pull software, software trending, uptime, etc...

Good Luck

I admit I'm a vendor of this product, so take this with a pinch of salt if you wish.

It actually sounds like you need desktop and server management rather than networkd management.

We deal with Intel's LANDesk Management Suite which can give you each of these. For more information, please visit our website below:

I hope this helps.

Mark.

you're looking for several products.
I doubt you will find a single product that will fill all of your requirements, although you may be able to find a single vendor.
hp OpenView is pretty decent and they have a multitude of products.
Network Node Manager for Layer 2 and Layer 3 devices.
ManageX or OpenView Operations for Windows for management of OS, Exchange and a plethora of other apps/databases. (They have a Unix product as well for hpux, solaris)
Service Desk for Inventory/Change Management/Help Desk.
and I think their software distribution is DTA?
(I could be mistaken on this one)
