SLOW VPN /w CiSCO CLIENT & MS ACCESS to SQL SERVER

Postby marcad2000 » Fri Dec 29, 2006 11:24 am

I am experiencing EXTREMELY slow VPN Kbits/s (in the 10 -20 Kbits/s range) across my DSL conntection which is reliably 2.5 meg down/450+ up.

I am using an MS Access frontend (local) application to SQL SERVER (remote).

All this runs though a Linksys RTP300 Router (local) to a large and sophisticated Data Center. I can transfer files to/from this server at normal speeds, but the Access/ODBC/SQL SERVER application is horribly slow, to the point that works is nearly impossible.

Any thoughts, suggestions?


Thanks,

We have found many people experience the same issue when accessing access or SQL database. You may try to run TS over VPN. Or modify the MTU.
