This started yestrday when trying to sync up my Ipaq 3955 via USB.
When I put my PDA into the cradle or use my travel USB cable I get the following message

"Cannot start communications with the Desktop computer. Remote networking could not start due to a critical error (Error 604)"

I have tried resetting my pda, I have also tried using activesync to re-establish the connection. So far no luck.

Has anyone seen this or have any ideas.

TIA
Robert

I contacted Compaq/HP support and this is the answer they have sent:

Dear Customer,

Thank you for contacting hp eServices.

This is with reference to your e-mail regarding the 604 error notification.

To resolve the issue, please follow the steps given below:
1. Disconnect the iPAQ from the Host PC.
2. Uninstall Microsoft ActiveSync on your Host PC (go to Add/Remove Programs under Control Panel).
3. Install Microsoft ActiveSync.
4. Reconnect the iPAQ, establish a partnership and synchronize.

Note: If you are using a USB connection, please try connecting the iPAQ via serial port. If the iPAQ is able to connect and synchronize with the Host PC, and the iPAQ is operational, you can take the backup of your data and perform a Hard reset. Most number of times, the communications error can be resolved by Hard resetting the iPAQ. Please check your User’s Guide for detailed instructions on performing Backup and Restore on your iPAQ.

Please e-mail us in case of any queries and we would be glad to help you.

Regards,
hp eServices


I have tried the removal and re-installation of Activesync with no success. When I get off the road this weekend I will try the hard - reset approach.
I will post as to the success or lack thereof.

PS. Never had these problems with my Jornada 545

To those interested.

I followed the steps outlined by HP/Compaq support.
I did a hard reset of my 3955. That made my USB port again available for syncing.

I restored my backup did a soft reset, placed the computer in the cradle to sync up and immediately received the Error 604.

I did another hard reset and then synced up with my serial port to see if that made a difference. Same results after restoring the backup.

This led me to believe that this was a software problem (ie application issue, or maybe some kind of PDA virus.

I copied my data files out to my desktop machine. Performed another hard reset, and then reloaded all my applications. I then copied the data files back to my PDA.

So far no problems.

If no problems occur for the rest of this week I will use this as my new backup.
