OD Cost Matrix Distance Accumulation Issues - Network Analyst 9.2

Hi All,

I am just wondering if anyone has experienced any distance accumulation issues in the resulting dbf distance file when undertaking a OD Cost Matrix with the use of NA in ArcGIS 9.2??

I am basically running a OD Cost matrix and NA repeatedly accumulates all the distances incorrectly. I have a number of road class types described within my network dataset that are required to be accumulated.

I have rebuilt the network a number of times, and also restarted ArcGIS several times however the issue persists. This is an issue that has only begun to occur recently, and does not occur on older network datasets that had been created with 9.2.

Has anyone possibly experienced this and know of a solution?

Any assistance would be greatly appreciated.
