Hi

I have a DNN site that has been working flawless for a few years.
Then came the time I needed to move the site to another server.

Now I can not login either as admin or host.
When I try to login, I'm sent back to the frontpage, with an "Cirtical Error - Object Instance not set to an...."
I get following fault in my Exception log...

<log LogTypeKey="PAGE_LOAD_EXCEPTION" LogGUID="a779ab50-5659-4e3f-a708-7e34006e0212" LogCreateDate="2006-10-20T13:37:05" LogCreateDateNum="20061020133705961" LogPortalID="0" LogPortalName="MyFaultySiteName" LogUserID="-1" LogFileID="931461f6-1e41-4df5-a466-9c870cc5fbea" LogUserName=""><p n="FileName"></p><p n="FileLineNumber">0</p><p n="FileColumnNumber">0</p><p n="Method">System.Web.Util.StringUtil.GetStringHashCode</p><p n="DatabaseVersion">2.1.2</p><p n="AssemblyVersion">2.1.2.17141</p><p n="PortalID">0</p><p n="PortalName">MyFaultySiteName</p><p n="UserID">-1</p><p n="UserName"></p><p n="ActiveTabID">27</p><p n="ActiveTabName">Forside</p><p n="AbsoluteURL">/Default.aspx</p><p n="AbsoluteURLReferrer">http://www.myfaultysite.dk/?ctl=login</p><p n="ExceptionGUID">ff08a90e-013e-4d28-8d3f-47b0842cadc7</p><p n="DefaultDataProvider">DotNetNuke.Data.AccessDataProvider, DotNetNuke.AccessDataProvider</p><p n="Message">Object reference not set to an instance of an object.</p><p n="Data">System.Collections.ListDictionaryInternal</p><p n="InnerException">System.NullReferenceException: Object reference not set to an instance of an object.

The site is running on a Win2003 IIS 6.0 and the Full trust is set.
The site is using Access.

I've tried to make a local copy of the site, and it works fine.

Please advice!

Thanx
