Following on from my post in relation to the CompactDBA solution - I thought it'd be useful to provide a detailed list of other management solutions so that IT professionals can manage their infrastructure from outside the office, whilst travelling and mobile!
The majority of products are only available for Pocket PC devices due to the larger screen size of the PPC. However there are some great solutions out there:
Command Line Access and beyond (Expand Beyond Corp.- PocketAdmin) - http://www.xb.com/products/pocketadmin
This solution gives you full command line and browser based access so you can securely manage the objects in your Active Directory as well as workstations and servers including mailbox and queue management within Exchange Server
They even have a free 15-day trial!
Fault diagnosis, user mgmt – (Avocent/Sonic Mobility – Sonicadmin)
This allows full fault diagnosis, user management and other capabilities - they have a very cool flash demo at: http://www.sonicmobility.com/products_sonicadmin.htm
