Troubleshooting Needed

Hi, we just started receiving the following error messages about 3
weeks ago. We don't get them all the time, or even on the same pages
necessarily, but we get them from time to time and our sql server
connection is slower in the last three weeks also. Our database is
remotely hosted, and the programmers are also offsite, so we are trying
to deal with this issue with our database server host, with no
knowledge of sql server. They say nothing has changed on the server,
but we haven't changed any of our front end files either, so we don't
know what the problem is. Here's 3 of the most common errors:

1. Microsoft Cursor Engine error '80004005'
Data provider or other service returned an E_FAIL status.
.../subview.asp, line 132

2. Microsoft OLE DB Provider for SQL Server error '80004005'
TDS buffer length too large
.../subview.asp, line 28

3. Microsoft OLE DB Provider for SQL Server error '80004005'
Unknown token received from SQL Server
.../members.asp, line 182


We have *no idea* what the above error messages refer to, or whether
this is something wrong with the server or the ASP pages mentioned. Any
help anyone could provide so we can understand the types of messages we
are getting would be nice.

Regards,
Sage
