I have an L73 with (2)1756-EN2T's and 52 Ethernet connection mostly flex IO and Powerflex drive a few E1 overloads. Problem is it keeps dropping communications to WW dasabcip and I cannot figure out why. I added the second EN2T and have only the DA Server looking at it and still with no luck. ver 21 firmware processor and ver 5.1 in the EN2T's. No joy from either AB or WW I have support from both. Anyone else seen this problem? oh almost forgot all network connections NOT set to auto negotiate and all set to 100/full.
 
What version of the DA Server? You'll have problems with anything prior to 4.1 SP3.
 
Look at the embedded Web pages in the 1756-ENBT to see if there are any physical errors being reported at that port. In my opinion, you have to eliminate the possibility of hardware problems before you go after controller capacity, software bug, or firmware issues.

It might be worth setting up a little alternate channel with RSLinx Classic or something else that has a diagnostic log, to see if other software clients lose their connection at the same time.
 
4.1 SP3 says it supports v20 firmware, you may need to move up to version 5 for v21 firmware support.

I agree with Paully.
Even on version 20 firmware, I have had problems with 4.1 SP3 that were cured by moving to version 5.
Just need to make sure you have an up to date licence for v5.
