asp - error of COM+ Admin SDK

[roshaan]

i am working in asp 3.0. and using this script....

objCDOSYSMail.From = request("txtFrom")
objCDOSYSMail.To = request("client_email")
objCDOSYSMail.Cc = "adm@adm.com"
objCDOSYSMail.Subject = Request("txtSubject")

'where client_email holds 10 email addresses
but during process it generates error

"(0x8004020E)
Cannot modify or delete an object that was added using the COM+ Admin SDK"

and when i change script like this one, it runs successfully

objCDOSYSMail.From = "abc@abc.com"
objCDOSYSMail.To = "xyz@xyz.com"
objCDOSYSMail.Cc = "adm@adm.com"
objCDOSYSMail.Subject = Request("txtSubject")

any suggestion, or any another alternate.
many thanks :)

What is the value passed to the server through that form parameter? Response.Write( ) it to the screen and post it.

solved-asp - error of com+ admin sdk

thanks for reply - Nicodemas - ....after some careful study finally i managed to solve the problem.and i am sharing my mistake, for others if they have same issue like this
here is my mistake,,
i just hard code the email address of (from) in this tag

 <input name="txtFrom" class="Text-Box" size="35" value="abc@abc.com">

and these three line were like this

objCDOSYSCon.Fields("http://schemas.microsoft.com/cdo/configuration/sendusername") = "abcxyz@abcxyz.com"
'and
objCDOSYSMail.From = request("txtfrom")
objCDOSYSMail.To = request("client_email")

and then, when i got your reply i again chk all my form values and email sending script, i finally managed to correct this problem.
so when script executed it was looking for

abcxyz@abcxyz.com
'in this line
objCDOSYSMail.From = request("txtfrom")

and form was sending something else, that was my mistake, then i again change this line

 <input name="txtFrom" class="Text-Box" size="35" value="abc@abc.com">
'to this
 <input name="txtFrom" class="Text-Box" size="35" value="abcxyz@abcxyz.com">

and script runs successfully without any errors.
-some times our little mistake is in front of our eyes but we don't know--:):):)
