It's here. 

With a logbook defined by 

 [test]
 Theme = default
 Comment = Test of auto-increment
 Attributes = Batch
 Subst Batch = %Y%m%d-##

the auto-incrementing of the Batch attribute within dates works when the logbook contains only entries for
today's date but otherwise will give a batch number of "01" for each entry.  

Changing line 8714 of elogd.c as follows, from:

      /* if date part changed, start over with index */
      if (strlen(attrib[index]) > 0 && strncmp(attrib[index], retstr, loc) != 0)
         old_index = 0;   
      else
         /* retrieve old index */
      if (atoi(attrib[index] + loc) > old_index)
         old_index = atoi(attrib[index] + loc);
to
      /* if date part changed, start over with index */
      if (strlen(attrib[index]) > 0 && strncmp(attrib[index], retstr, loc) != 0)
         break;            /* <------------- */
      else
         /* retrieve old index */
      if (atoi(attrib[index] + loc) > old_index)
         old_index = atoi(attrib[index] + loc);

appears to fix this bug when I test it.  This code is inside a loop stepping back through all log entries, and
the variable old_index is already set to zero before the loop. The existing code resets old_index whenever the
prefix of the attribute string (containing a date) does not match the "current" value of that prefix as found in
retstr (set using strftime).  So, if there are any records for dates other than today then old_index is reset
and attribute values will be set with the counter = (old_index+1) = 1.  The modified version stops comparisons
once a different date is seen, but assumes that records are date ordered.  An alternative patch:

      /* if date part matches */
      if (strlen(attrib[index]) > 0 && strncmp(attrib[index], retstr, loc) == 0)
          /* retrieve old index */
         if (atoi(attrib[index] + loc) > old_index)
            old_index = atoi(attrib[index] + loc);
  
does not make this assumption and also appears to work OK when I test it.

This must be related to the unknown cookie "style". There was some work recently on elog to make it robust against unknonw cookies. The latest modification was on version 2192, and you probably have an older version. I made a release elog276-2.exe for you. Try it and let me know. You can also just delete your cookies in Firefor and it should be fine, but it's better not being able to crash elog. 

 Thanks for the feedback, I found the problem, someone installed the AVG toolbar in Internet Explorer in the computers, and for some reason the AVG Error Redirection option prevents Elog from opening in Internet Explorer.

No, there is no Dotnet or DLL required. Just start the ELOG server manually by clickin on Start/Programs/ELOG Server/Start ELOG server manually and watch if you can spot any error. One person reported that downloading again the package solved a similar problem.

We are currently having problems with Elog, I never had a problem installing it before but with my last 3 install I can't get it to work. We are running under Windows XP, the installation works perfectly but when I try to use the shortcut pointing to the localhost 8080, I get an error page from Internet Explorer telling me that the server cannot be found. I've rebootied the computer to make sure the server was running but still the same problem. Is there a basic requirement I should look at (Dotnet versionX or specific DLL required)?
