Hi Bruce,
I´m not using any SMPP functionality but i´m getting this error compiling a solution:
749: unkown procedure label                 NetSMPP.clw
749: Field not found: SPLITEVERY       NetSMPP.clw
this is a big multi-dll solution that i´m using nettalk but not smpp. this error start after upgrade to nt 6.26. 
what´s wrong?
thanks
