Hi All,

SQLState HYT00 timeout expired .

I have tested the network from the client to server and see no slowness and the ping is stable. the user will connect after clicking the message, my SQL application is client/server and I don't user any ODBC.

HYT00 errors are network layer associated. Thus it maybe really that these users have a network problem (nic, switches).

Where do they get the error? When connecting or executing SQL statements? Consider using SQL Profiler..

Gosh, what does this mean? Open the application? Are you the developer of this application, a DBA of the servers behind or just the guy to fix it?

It always the same users having this issue?
It always occurs at the same time of the day?
It always occurs in the same option inside the application?
