Active Directory Membership Provider Performance

by dcurtis 11/26/2008 6:47:00 PM

I am developing a site for a customer using the Active Directory Membership Provider for authentication.  The first time you logged into the site, it would take about 45 seconds.  Subsequent logins would be fast; however, after two or three minutes, the authentication would be slow again.

I searched several different groups for a solution and initially could not find anything.  Finally, I found the solution here.  Essentially you have to give permissions on the %SystemDrive%\Documents and Settings\All Users\Application Data\Microsoft\Crypto\RSA\MachineKeys folder to the Network Service user.  Once I did that, everything authenticated quickly.

 [Update]

This actually didn't fix anything.  I ended up having to write a batch script that keeps pinging the site to keep it active.  This keeps things active the majority of the time; however, ocassionally it still takes awhile to authenticate.

Error on Photoshop CS2 on Vista: "Unable to continue because of hardware or system error.."

by dcurtis 11/12/2008 8:43:00 AM

This morning when I tried to open a PSD file in Photoshop, I received the following error: "Unable to continue because of a hardware or system error. Sorry, but this error is unrecoverable."  I performed a search on Google and found what I thought was a solution here, but none of the suggested fixes worked.  The site suggested that it might be because the event log manager might be turned off, so I thought I would check the event logs.  Upon checking the logs, I found the following error:  "Source: Outlook Category: None Type: Error Event ID: 35 Description: Failed to determine if the store is in the crawl scope (error=0x80070002)."

 Performing a search on that error led me to the following thread: http://www.microsoft.com/communities/newsgroups/en-us/default.aspx?dg=microsoft.public.outlook&tid=a681f8a4-f6e1-456b-86fe-1469fc04b16f&p=1

 I followed all of the instructions posted by Marphyre and it not only resolved my problem with Outlook, but it resolved the Adobe problems as well.

ssvagent.exe warning when starting IE on Vista

After I installed java 6 update 10, I started receiving a warning every time I opened IE.  After uninstalling update 10, the problem went away.

Maverick.Net hmmmmm

by dcurtis 11/5/2008 10:07:00 AM

I have a potential customer who is using, what appears to me, to be an obscure .Net MVC framework called Maverick.Net.  In trying to understand the framework better, I downloaded it from sourceforge and attempted to install it on Vista/IIS7 and compile it with VS 2008 targeting the 2.0 framework.  AHHHHHHHHHHHH!  What a painful process!  After several hours I finally was able to (I thought) update all of the code that was now obsolete and get the Friendbook project to run.  The framework is interesting--it is essentially a mash-up between ASP and a C# class library.  While I understand the concept a little better now that I've seen it working, I think it still leaves something to be desired.

 I still can't get the Calendar or Friendbook-xlt example applications to work properly--I think partially because I'm not sure I updated all of the obsolete code properly.  Anyone have a good copy of Maverick.Net ported to 2.0 that actually works properly?
