I cannot for the life of me figure out why I cannot wrtite a file to a directory inside of the website. I have this working on a Windows 2003 Server using IIS6. I've ported this web app to a 64bit Windows 2008 server and I am unable to have my web app write a file to a directory. I have shared and given security access to everything under the sun on this server to that particular folder and still no luck. My dev workstation with Visual Studio 2010 has no probelm saving a file to that directory. So it has to be something with the web server account. I am using Windows Authentication. I have an account in our Active Directory that is being used.

We just replaced our network server. The new server uses CIFS (I am not a server person so I know very little about this). Accessing the virtual directory on the old server, I could access information using static links, asp and aspx.Trying to access information on the new virtual directory, none of my dynamic links work. I can create a static link to a specific file with no problem. My asp pages return "Path not found" and the aspx pages give me the "Logon Failure: Bad username or password.

I'm developing an intranet site in asp.net 3.5 using linq to sql. When I run the site on my development system, it works great. I moved the site and SQL Server database to my CLient's Server for testing.
When I execute the following vb.net code
Dim linq1 = From PageGroup In dbs1.ZZ_PageGroups Where (PageGroup.PageName = pasPageName)
For Each PG In linq1
I get the above error message. I suspect the problem may be authenticating the user in SQL Server. When using Linq to SQL, how/where is the connection string set and how does it know the user?

I have an app that uses impersonation to gain access to a database (on server separate from IIS). The app connects to the database using a trusted connection and seems to be working just fine. However, we get these logon failure events in the security event viewer:
[Code]....
It must have something to do with impersonation because the login failure is for the domain account which my app is impersonating under. But again, the app is working fine so I'm having a hard time figuring out how to stop these logon failures.

I have a domain controller on windows 2008 server R2, The users are able to modify their password through a web page. Once it's done, the users are still able tu use the old password as well as the new one at the next logon. The old password is still active only one time after the change, after that it's no more possible to use it...
I invoke the "ChangePassword" function.
Is it a parameter to configure on the server ? Is it cached somewhere on the computer of the users ?
Here is my code:

i have a Error :
<forms name="appNameAuth" path="/" loginUrl="~/login.html" defaultUrl="index.html" </forms>
Server Error in '/' Application.
Access is denied.
Description: An error occurred while accessing the resources required to serve this request. The server may not be configured for access to the requested URL. Error message 401.2.: Unauthorized: Logon failed due to server configuration. Verify that you have permission to view this directory or page based on the credentials you supplied and the authentication methods enabled on the Web server. Contact the Web server's administrator for additional assistance.
The web.config in folder admin of my
<?xml version="1.0"?><configuration><system.web> <authorization><deny users="?"/><allow users="admin,administrator"/><allow roles="admins,administrators"/><deny users="*"/></authorization></system.web></configuration>
In file Global.
routes.MapPageRoute("login", "login.html", "~/login.aspx");routes.MapPageRoute("default", "index.html", "~/index.aspx");
If I use extensions .aspx, it runs normally

I am using Integrated Windows authentication and Role based authorization.The web.config file has two Active Directory groups.Sample code of web.config file for Role based authorization (Actually I got this sample code from a moderator of this site Gary works well).
Code:
<location path="Bloodgroup.aspx">
<system.web>
<authorization>
<allow roles="MedcenterGroup1"/>
<deny users="*"/>
</authorization>
</system.web>
</location>
So user's who doesn't belog to "Group1" AD group, should get Unauthorized error. It works exactly like that. But, before getting unauthorized error, it shows a pop up screen (as shown in the attached picture) prompting to put userid and password. If a user in AD group "Group1" accesses "Blood group. aspx" page, popup message doesn't come which is correct. Following is the code in web.config file to handle errors:
Code:
The <customErrors> section enables configuration of what to do if/when an unhandled error occurs during the execution of a request. Specifically, it enables developers to configure html error pages to be displayed in place of a error stack trace. -->
<customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
<error statusCode="401" redirect="Errors.aspx" />
<error statusCode="403" redirect="NoAccess.htm" />
<error statusCode="404" redirect="FileNotFound.htm" />
</customErrors>
Question 1: why does the popup box prompting user id and password comes up?
Question 2: I have put in web.config file in customErrors tag to direct to Errors.apsx page when I get 401.2, it should be redirected to Errors.aspx page. But it is not getting re-directed.

I've got an MVC 2 app that works fine when launching from VS 2010. However, when I deploy (using File System on the server in the same box) and attempt to run I get the error shown below. The wierd thing is that the Physical path shows: C:inetpubwwwrootWorksheetsSiteWorksheetsAccountLogOn which leaves out the "View" folder in the path.

I've got an asp.net application which I've deployed to my shared hosting provider. I've modified the connection string to point to the MySQL database stored on the shared server, and the page loads correctly.
However, when I run the page through the internet (as opposed to through VWD2008), I get an error:
Unable to connect to any of the specified MySQL hosts.
I'm not sure where I've gone wrong. The MySql.Data.dll; MySql.Data.Entity.dll and MySql.Web.dll are all in the /Bin folder.

This problem is driving me absolutely crazy. I developed a very simple Web part and overrode the CreateChildControls to load a user control. The user control contains a ScriptManager and UpdatePanel from System.Web.Extensions. This Web part appeared to be working fine for weeks and all of a sudden today I get the error:
Unknown server tag 'asp:ScriptManager'.

Several production websites running for months with no problems, all of sudden now fail to compile sporadically.
The compiler will generate errors:
ASPNET: Make sure that the class defined in this code file matches the 'inherits' attribute, and that it extends the correct base class (e.g. Page or UserControl).
On master page code behind files that it did not before.
In addition, this error will go away (most of the time) if we recycle the application pool.
