You and I are on the same wavelength. I put in a request to see if they are. I know that certain types of DNS lookups (in Windows 2000+ AD environments anyways) will use UDP instead of TCP. This very well could be the issue. I haven't had a chance to research the particulars myself, but it sure seems a likely candidate at this point. ------------------------------------------------------------------------- Using Tomcat but need to do more?
