SUMMARY

This article describes how to use the Nslookup.exe utility which comes with Microsoft Windows NT and Microsoft Windows 2000 to look up an RVP protocol record for Exchange Server Instant Messaging software.

MORE INFORMATION

To use Nslookup.exe to look up an RVP record:

Open a command prompt.
Type nslookup, and then press ENTER.
Type set q=any, and then press ENTER.
Type _rvp._tcp.domainname.com., where domainname.com is the name of the domain that you want to verify the RVP record for, and then press ENTER.

The following section is an example of an Nslookup session:

_rvp._tcp.microsoft.com SRV service location:
          priority       = 0
          weight         = 0
          port           = 80
          svr hostname   = im.microsoft.com
