We are currently running into an issue with a third party app [HEAT Helpdesk] that has an ODBC connection to a SQL database. we will randomly see one of our applications crash with an ODBC error. [connection refused] sql error 67.
we have found that to work around this issue we need to do an ipconfig /registerdns to get connection reestablished with the DB. also if we put a static hosts entry into the hosts file the issue is worked around. These work arounds are pointing to a dns issue i believe. so here is the DNS debug [10] output. If sombody more grounded with name resolution would be so kind as to identify the error in the logfile.
