The transport failed to connect to the server. ASP, VBScript

[munro01]

Hi,

I am a newbie to ASP and VBScript. I have a bizzare error that I have been trying to trouble shoot for about 2 days now. Essentially I have been jumping from one website to another to try and solve the problem.

Problem Description:
I am trying to use VBScript To Send Email Using CDO and this is code I have for it (with the credentials filtered)

 
sub request_recommendation(ID)
 
    insert_recommend_request(ID)
    dim cname
    cname = get_reference(request.form("csmp_id"))
    dim strSubject, emailText
 
    strSubject = "Recommendationp"
    emailText = "<b> " & cname & " is testing this email functionality.<br/>"
 
    'Create the mail object
    Set objMessage = Server.CreateObject("CDO.message")      
    objMessage.TO = request.form("email")  
    objMessage.From = "[e-mail]"
    objMessage.Subject = strSubject   ' Specify the subject line
    objMessage.htmlBody =  emailText
 
    'Configs
    objMessage.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendusing")= 2
    objMessage.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "smtp-server.com"
    objMessage.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = cdoBasic
    objMessage.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendusername") = "[e-mail]"
    objMessage.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendpassword") = "mypassword"    
    objMessage.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserverport") =25 
    objMessage.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpusessl") = False
    objMessage.Configuration.Fields.Update
 
    'Enable send
    ON ERROR RESUME NEXT
    objMessage.Send
 
    set objMessage = nothing
end sub    
 

When this function is executed (called from a view) I am getting this error: "The transport failed to connect to the server." The odd thing is that this same code was working perfectly about a week ago but this error started occurring 2 days ago. I have double checked the code for any typos but I don't see anything wrong with it.

Someone mentioned that this may be due to a network problem. "They suggested checking to ensure the server System.Web.Mail is executing and can connect to the mail server. Because sometimes firewalls or proxy servers can get in the way."

Is anyone familiar with:
1)How to check if the server is executing and connecting to my mail server.
2) How to check if firewalls or proxy servers are getting in the way.

Detailed steps on how to carry out these checks will be greatly appreciated because I am not sure what the problem is and I am speculating that this may be the issue.

Any other suggestions may be helpful too but YES I have looked up a lot the forums that google returns and they haven't been helpful so far.

Thanks
