Random Slowness in SalesLogix v7.5.1 Web and Windows Event Viewer Error Logs

Question: Our users are on SalesLogix v7.5.1 Web and have been experiencing random slowness.  The Windows Event Viewer on the IIS server shows the following errors:

Log 1–>
ERROR Sage.SalesLogix.Web.SLXMembershipProvider – cannot open connection

Log 2–>
ERROR NHibernate.Util.ADOExceptionReporter – No error message available, result code: DB_SEC_E_AUTH_FAILED(0x80040E4D)

Log 3–>
ERROR NHibernate.Util.ADOExceptionReporter – cannot open connection

Log 4–>
ERROR Web Host – Connection Exception: No error message available, result code: DB_SEC_E_AUTH_FAILED(0x80040E4D)

Why might we be receiving these errors?

Answer:  You are seeing this sequence of events being logged because of a failed login.
Try the following steps if you would like to test:

Open up a Connection to your SalesLogix Web Client, but don’t login. Populate a bad username/password combination.
Clear your Event Log.
Click on the login button.
You should notice that the 4 entries you listed above are recorded.  When you login with valid credentials and they are not.
