Environment: Windows 2003 server, AD integrated DNS

Hi there:
I'm having a devil of a time tyring to do a delete/replace all A and www records in 1000+ DNS records for our websites (the IIS server has moved to another IP address (67.155.1.103)) and I'm also trying to set up a new DNS server.  I am on the new DNS server and all DNS zones have been set up, but they have the old A and www records pointing to the IP address of the old IIS server.
I have written two batch files and I am executing one against the other.
One .bat program has all the website names and I am doing a  
for %%1 in (
domain1
domain2
...etc.
) Second_bat_file

The second .bat file against which the first program is executing has the following dsncmd commands:

dnscmd /recorddelete %1 @ A www /f
dnscmd /recorddelete %1 @ A 67.95.76.244 /f
dnscmd /recordadd %1 @ A www  67.155.1.103 /f
dnscmd /recordadd %1 @ A 67.155.1.103 /f

From the commands, you can see I am trying to delete the A and www records in each DNS zone and replace them with new a and www records.

When I run the program batch file against this second one, it keeps giving me invalid syntax or missing syntax errors . The program goes through all the websites (and gives all the errors), so I don't see a problem with the first .bat file that contains the for/do program and the domains.  The problem appears to be in my syntax in the second .bat file that contains the dnscmd lines. What am I doing wrong? I have tried all kinds of combinations and nothing works.
Thanks

The error is in your first script.
The "for" command has to be used with letters from a to z or A to Z, and you didn't pass the variable to the second batch script, either.

for %%a in (domain1 domain2 ...) do call SecondFile.bat %%a

Thanks. So I replace the "1" with an "a" in the first script. Does the "a" variable also have to appear in the second script. If so, where does it appear in each dnscmd line?
Thanks

The "%%a" variable is only visible in the "for" loop.
It is then passed using the command line to the second batch file (and the first command line argument in the second batch is then %1).

Excellent! Thanks for the help. I'm assuming I can have multiple dnscommand line arguments in the second batch file.
