• May be helpful: Ngen.exe executequeueditems

  Post 5 on MS07-040 issues (see Ngen Patch ): From: http://www.theregister.co.uk/2007/07/12/ms_patch_problems/comments/ MSCORSVW.EXE By Steve Coffman Posted Friday 13th July 2007 01:13 GMT Luckily my system didn't go haywire after installing the .NET patch, but afterwords I noticed a new process running called mscorsvw.exe. I run my XP system pretty lean and mean and have disabled all non-essential services and processes (I only have a total of 4 non-MS processes and 4 non-MS services that load on startup...) so I was curious as to what it was. Doing a quick web search, it turns out it is a background compiler for .NET assemblies. Theoretically it is supposed to compile the assemblies during idle time (it is set to lowest priority) but mine wasn't doing much of anything while my system was just idling. The info I found says if you run the command ngen.exe executequeueditems from the .NET folder (mine happened to be in C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727) it will force it to process Read More...

• MS07-040: good advice from Swa Fantzen

  This is my 4th post about MS07-040. Read all related posts here: Ngen Patch . Swa Fantzen says in MS07-040: .Net Update Trouble : ... We'd like to offer a double advise at this time: If you run into trouble do call Microsoft and open a case, it's the only way to get attention to the problem from those who know best how to fix it. It should be free. In the US: call 1-866-PCSAFETY, check their website for other countries, support with patches should always be free. Do read through for your specific combination of .NET framework version and you specific OS the relevant KB, some of them were prepared in anticipation of certain problems. They are all linked from KB 931212 . ... Read More... Posted Friday, July 13, 2007 4:15 PM from Rob Relyea | 0 Comments Filed under: Ngen Patch

• Is the 2.0 patch based on 2.0 that shipped in Vista?

  3rd post in a series about a patch that MS released this week that slows down computers (with lots of disk activity) for a while. Read all my posts here: Ngen Patch . These Comments came from a comments section on The Register. We experienced a break with our product at work Posted Thursday 12th July 2007 17:29 GMT I work for an ISV, and the update broke our product. We're still scrambling to make sure that all our customers are okay. We investigated the reason for the break, and we're 99% sure that the change that broke our product had no security impact whatsoever. It is, however, a change that has been made to later revisions of .NET. It looks like, rather than releasing a patch just for the security issue they were trying to fix, Microsoft actually pushed their latest code version, with lots of changes that were previously Vista-only (or part of the later versions of .NET?) Feels to us like Microsoft are taking short-cuts with security, and ignoring the customer impact. A few hours Read More...

• NGEN Background

  2nd post in a series of posts about Ngen Patch which slows down your machine during an update (and perhaps after for several minutes), but should leave everything fine afterwards. Some more details: During install of the .Net Framework, many DLLs are placed in the GAC (Global assembly cache) and then during the install, most of them are NGENed, which means that a Native Image dll is created that can be run much faster than the DLLs that have been installed initially. This optimization takes several minutes (depending on the speed of your CPU and disk) and uses CPU and disk resources. When a DLL is patched, other DLLs that depend on that DLL need to be re-NGENed. .Net 1.1 and .Net 2.0 are different in how they NGEN. .Net 1.1 NGENs syncronously and .Net 2.0 has an NGEN service which can NGEN over time.

• Update to .Net Framework - appears to make your system very busy for a while...

  Rob Eisenberg blogged on the 11th that the updates appeared to break WPF (make it very slow). Engaging with him, our team figured out it wasn't the Office patches that he thought it was, but it was an issue with the re-NGENing of assemblies after 1 or more patches to the .Net Framework. This morning, I saw an email from a colleage that the issue had been slashdotted and mentioned on The Register . It appears that this is impacting many systems...where they are busy doing a bunch of work, by a service that is just trying to get assemblies NGENed appropriately. I figured blogging about what we know, early, will help people deal with with it...information will minimize the impact. MS07-040 - addresses a vulnerability in the .NET Framework was one of the 7/10/07 updates. Some Quick background. .Net 1.0, 1.1. and 2.0 were patched. .Net 3.0 systems require .Net 2.0 If you have .Net 1.0, 1.1 and 2.0 on a system, I believe all the patches will be installed. We're sorry for any impact, and want Read More... Posted Friday, July 13, 2007 3:08 PM from Rob Relyea | 0 Comments Filed under: Ngen Patch
