Login Failed for user DomainName\machinename

 NETWORK SERVICE and LocalSystem authenticate themselves always as the corresponding account locally (builtin\network service and builtin\system) but both will authenticate as the machine account remotely. This can cause login failures.

If you see a failure like Login failed for user 'DOMAIN\MACHINENAME$' it means that a process running as NETWORK SERVICE or as LocalSystem has accessed a remote resource, has authenticated itself as the machine account, and was denied authorization.

A typical example would be an ASP application running in an app pool set to use NETWORK SERVICE credential and connecting to a remote SQL Server: the app pool will authenticate as the machine running the app pool and is this machine account that needs to be granted access.

When access is denied to a machine account, then access must be granted to the machine account. If the server refuses to login 'DOMAIN\MACHINE$', then you must grant login rights to 'DOMAIN\MACHINE$' not to NETWORK SERVICE. Granting access to NETWORK SERVICE would allow a local process running as NETWORK SERVICE to connect, not a remote one, since the remote one will authenticate as, DOMAIN\MACHINE$.

 

What you need to do to fix this is open IIS manager open up the advanced view for the particular app pool, and change it to run as yourdomain\yourusername, add the password, and restart the pool.


Obviously this isn't a perfect fix because when password changing time arrives, you may need to go back to IIS and change the password.

Some observations on Script Callbacks, "AJAX", "ATLAS" "AHAB" and where it's all going.

I've taken a more than cursory interest in the whole Remote Scripting (.NET species) vs. AJAX and now ATLAS discussion, mostly because I started using Remote Scripting since Microsoft first released it, and because I continued to refine it after seeing Brent Ashley's excellent work with JSRS, which was one of the first "real" cross-browser solutions back in 2000 (that's the turn of the Century for you history buffs). Now Bertrand Leroy, a Microsoft guy whose work I like , has authored some very interesting ASP.NET 2.0 script callback stuff that he points to on his blog, and he is obviously (at least, to me he is) involved quite heavily in the development of this new ATLAS infrastructure that they'll preview at PDC. Leroy's most recent post brings to the surface what I agree are the major differences between the "AJAX a - la .NET" approach as popularized by Michael Swartz with his AJAX.NET library, and Leroy's RefreshPanel, the ASP.NET 2.0 b

IE7 - Vista: "Internet Explorer has stopped Working"

Image
This one was a bitch. All of a sudden for no reason at all, out of the blue, I get this dialog "internet Explorer has stopped working". I didn't install any new software, crap- I didn't do anything! So here I am using FIREFART to go on the internet and find out what to do! Damn! Good thing I've got the sucker on the same machine (I'm not "anti-Firefox", i just don't use it that much except to check my page renderings). The Fix The fix (at least for me): 1) Go into Control Panel, and choose "Internet Options". 2) Under the "Advanced" tab, press the "RESET" button at the lower right: Don't ask me why this happens, or why the fix works. That's a BUG, D00D - I don't care how you slice it!

FIREFOX / IE Word-Wrap, Word-Break, TABLES FIX

One of the most annoying things a developer (who would normally delight in writing code, not futzing with markup) can have is getting rendering issues between different browsers. The two biggest players are of course Internet Exploder and Firefart (as I lovingly like to refer to each). In most cases that's going to take care of 98 percent of your total site traffic. IE has had a proprietary "word-break" style attribute for a long time, and this made it into the CSS 3.0 spec. But that doesn't necessarily help you with Firefox right now. Firefox literally - (and I consider this completely idiotic, since it's been in their bug database for FIVE YEARS) does not have a reliable CSS style element to force table cell content to break in the middle of a word in order to stop the content from expanding your table / div off the page or over other content on the page. Here's a partial fix, which will work for most tables and browsers. The style declaration (I call it m
