Thanks, Cetin,
I'll pass your ideas along to the Network Admin who's arriving Saturday to work on this. We ARE able to index quite easily, even files of 50MB or more with 10-15 indexes, from a workstation.

>It's the network I think. But I don't know how to really show it's network. Maybe with a simple routine in front of network admin's eyes. Select a large table and use it excl than index on any expression from a station. I think it will stop with "File read error" (at least happened to me). The same routine runs perfect if files are on a station or directly run from NT. BTW mine was a 10 Mbit network and IDE disk on NT. I think it's related with NT caching and paging but currently doesn't have a solution.
