Using slurpd in win2K, slurpd will fail to start if the replog file does not
exist.

This will usually occur when a directory is first instantiated - say after a
manual sync between two directories prior to replication.  The replication file
will never have been written by slapd as no updates will have been made to the
directory.

Work-arounds include forcing a change to some record in the directory to get a
replication file created.  This is not a good solution when slapd and slurpd are
installed as services that automatically start.

A fix could include slurpd creating an empty replication file if it doesn't
already exist.
