VBS/IIS error '800708c5' in ADSI changing password

[jdemars]

I am getting an error '800708c5' in a IIS script when trying to change a user account password via a web page. I have the following code:
[tt]
oldpassword = Oldpwd
newpassword = pwd1

SamID=left(user,instr(user,"@&quot-1)

response.write &quot;Sam ID is &quot; & SamID & &quot;<BR> and User is &quot; & user & &quot;<br>&quot;

Set namespace = getobject(&quot;LDAP:&quot

Set ADS_User = namespace.openDSObject(&quot;LDAP://mydc.domain.net/CN=&quot; & SamID & &quot;,OU=varteconline,DC=varteconline,DC=net&quot;, &quot;domain\administrator&quot;, &quot;deleted&quot;, 513)

if err.number<>0 then
errorstring = errorstring & &quot;There was an error resetting the user password. Error 2C1.<br>&quot;
else

response.write &quot;old pwd is &quot; & oldpassword &&quot; and new is &quot; & newpassword & &quot;.<br>&quot;

ADS_User.ChangePassword oldpassword,newpassword
response.write &quot;Completed.&quot;
end if

[/tt]
When I run this code via IIS, the web page displays:
-------------------------------------------------
New PWD is abc123Sam ID is detest3
and User is detest3@domain.net
old pwd is password and new is abc123.
error '800708c5'

/x/ChangePassword.asp, line 266
-------------------------------------------------
Line 266 is ADS_User.ChangePassword oldpassword,newpassword

My domain has a minimum password of 1 character, does not have complex passwords required, does not have password history enabled. This is not running on the domain controller, but mydc.domain.net is a domain controller.

I know the call is getting to the DC, because if I put an invlaid password in for teh source, it gives me a different error.

What I am trying to do is allow my network users to change their passwords via a secure web site without needing anything more on the remote end then a web browser.

I do not have SSL running within my network (to the best of my knowledge), only between the user and the web server.
