Connection takes a long time (around 10 seconds)

---

Normally the connection to the server should complete very quickly – less than a second in most cases. If you find that it is taking a long time there may be one of two problems:

• Misconfigured reverse DNS.
  • CVSNT does a reverse DNS lookup on startup to verify the client hostname. This will usually complete very quickly, however it is possible to misconfigure the reverse DNS in such a way that the lookup hangs and eventually times out after around 10 seconds. Your network administrator will usually be able to sort this out in a few minutes, as its usually a simple misconfiguration. On NT4 machines there is a setting “Use NetBIOS for DNS resolution” which may help. (Q: Is there an equivalent for W2K or do they always do it?)
• Very slow connection to PDC
  • CVSNT needs to contact the PDC to verify identities and check privileges. Normally across a LAN this will be quite quick, but over a saturated network or over a Dialup (in local mode) it can be very slow.
• See also http://support.microsoft.com/default.aspx?scid=kb;en-us;Q308512 for a possible solution.
• Another thing to try: Disable the virus checker on the machine that hosts the CVS server.
