Remote Desktop momentarily drop connection every 18 seconds...

We are running 5 T1 lines to our remote offices. We have Adtran 3205 routers on each end.

The configurations on each Adtran have been configured for years and working very well.

We recently installed 1 3750G and 5 2960G switches with the 2960G trunked into the 3750G so they can route to remote networks.

The T1's are new circuits since we moved to new offices. We have had ATT check the circuits and they are clean with very low noise.

I can ping and tracert from either end with very low round trip times.

When I remote into the far end server with Remote Desktop, the connection momentarily drops connection consistently every 18 seconds on all T1's.

I have changed MTU settings on the Adtrans and turned off Spanning Tree on the 3750G with no luck...

Does anyone have any ideas on what this could be?

I can direct connect my laptop to the Adtran via crossover cable and the connection is rock solid.

Need some help...

Hi Bob,

Could you post your configs?
