dirkdigs 921

all of a sudden when trying to launch one of our application on the windows server internet explorer is prompting for user/pwd. It says the "The server reports that it is from digest" What is going on? Can you help? How can i turn this off. I tried many known credentials and they do not work . What account is it asking for ?

@dirkdigs Sometimes, IE will recognize Intranet site as an Internet site, when you access the intranet Web sites that require authentication,you may be prompted for credentials. you can refer to this KB, verify if it meets your situation. intranet-site-identified-as-an-internet-site.

Escalate to your domain administrators or server administrators, as that dialog indicates connection issues to domain controllers in general. There isn't much you can do.

there is only 1 server in play here and its on a WORKGROUP.
So i have no idea what credentials it is looking for.
i tried adding the site to local intranet and trusted sites but it was already listed in that location.

@dirkdigs Will you also be asked to enter your username/password when you run the application locally? you can try the username/password of your machine.

not sure what you mean by locally?
the program is installed on this workgroup server
i have changed the administrator password and logged out , then logged back in .
it still asks me for credentials. i put in the known good credentials but it does not work .
do i need to reinstall Internet explorer

Then it is by design. For WORKGROUP machines, there is no shared accounts (which is only available when machines are domain joined).

@dirkdigs Did you use a fully qualified domain name (FQDN) or an IP address?
