Im trying to test GMS on my company's Groupwise server. I've installed
Groupwise Mobile Server, got new IPAQ hw6915 and now I'm stuck on GMS Client

After installing "Over the Air" client (sending mail to PDA with
installation link), I can't connect with Intellisync Sync to Mobile server,
error is: Communication link lost (0x10A), when i'm looking at progress
details it pass first few steps (Generating keys, Exchanging keys) and then
stops on: Negotiating Security protocol.
Also I can't see my new (and only) device under devices on GMS
administration (MMC).

I've tried connection through Wi-fi and through cradle, result is the same.
Where should I look for a problem: on GMS server or on PDA?
Thank you,
