I have seen this many times.
It is probably easiest to restart the ColdFusion service.
That usually solves the issue.

hi, have u got this error solved? does any changes made to the Windows 2003 server on that day? apparently there are similar cases reported and it happen after SP2 is installed to the server. there are three possible ways of correcting the problem:

1- in the Data Source setting, choose Advanced Setting. un-checking the option "Maintain connections across client requests". this option should make ColdFusion reestablish the connection of each query
2- go to the properties of the GigNIC adapter and turn off TCP Offload
3- uninstall SP2

OP Zaharin,

Option 1, I'll have to discuss with contractor for web site

Option 2, there are three(3) settings for TCP offload.  Should all three be set to OFF
               Received TCP checksum
               TCP Segmentation
               Transmit TCP Checksum?

I have to resize the partition before SP2 can be installed so option 3 is irrelevant.

- if you did not install SP2 then option 2 is also irrelevant. this leave you with only option 1 from my suggestion.
