Four seconds is the conventional DNS timeout value. Some months ago we discussed such delays, which have been evidenced in a minority of sites (but not others) under TSM 5.2. This resolves to site issues in conjunction with the new DNSLOOKUP option (see the manuals, or http://people.bu.edu/rbs/ADSM.QuickFacts). It may be that 5.2 is illuminating some historic DNS issues in your shop. You don't specify your TSM patch level (V.R.M.patch_level), but make sure you are at a reasonably high level. Richard Sims
