Hi Everyone - appreciate some help

Have to host a DNN site - and am wanting help on how to get the users to login. The site appears to be working and is looking fine under IIS. However it is  not possible to login as an administrator or a normal member.

A bit of history - I have a SQL backup file and a zipped directory of the current live site (DNN v4.03.07) I have the site workng and the SQL Server 2003 talking fine.

I have made sure of the following

1) The Database is correct settings via the web.config (database, usercode, password) 

2) The Machine Key in the web.config has not been changed from the backed up version as given to me

3) I have flushed Cookies before trying to login (as suggested in some threads)

I still cannot login.

Can anyone else provide a list of things that they have had success with

I cannot do the suggested route of making a fake user and then substituting the password to the desired user is just not usable as there are over 100k users with a login.

So really reawlly need suggestions as to why this is not working - I am sort of at my whits end trying to sort this out.

It is a completely clean install and there is only this on the server - so I can do some really major tear-ups of need to debug this thing

ANY help is appreciated at this stage

Thanks for reading and geting back if you are able to help

Thanks for the reply I am not (as far as I believe) running IIS 7 - I am on Win 2k3 Server with MS SQL Standard - the DNN is a seperate Website haning off the root of C: I am all up to date on patches and fixes along with the service packs. Even if it is possible for pointers to where I can look further for documentation. I also started to write a login emulation process to see if I have the right validation keys (I have been assured from the current hosting environment that I have) but this is like so many other caes where the Machine Keys are wrong. So if anyone has an ofline resource to be able to check the user/name/machine keys - that would also be good. Thanks - and look forward to any moer suggestions please

Hi - it is as you suggest - the directory has full file permissions for the Network Service account

Thanks for the help so far - this is baffling me and I am not sure what to do on this - any other suggestions?
