Re: Windows cannot log you on because your profile cannot be loade

I don't fully endorse Brian's article because some of his comments include incorrect facts. The other problem I have with it is all of the comments--they serve to confuse the reader on what is a complex topic to understand.

What I have noticed is that people come to false conclusions after reading the article and comments of others, as well as statements made elsewhere on the web, specifically:

- Use of PAE switch is bad in a 32-bit TS environment. The truth is that this *may* be bad or it may not, depending on the specific circumstances. It is the same type of thing as saying that XX server specs will support XX number of concurrent users--it is too broad of a statement.

- Putting more than 4GB in a 32-bit TS server is pointless. This *may* be true in some circumstances, but in many cases (especially 2003) this is false.

- 2GB of physical memory is used by the OS, which only leaves 2GB for user applications on a 32-bit TS with 4GB of RAM. Again this is false and shows a misunderstanding of virtual versus physical memory.

Now I think Brian made an excellent attempt to summarize what is a complex topic, but I think the article falls short and doesn't explain things in enough detail. This combined with incorrect facts leads to confusion I believe for many readers.

I like Brian's articles in general but more for the "big picture thinking" aspect then their technical details.

When teaching this subject to others I like to walk the person through excercises where I artificially create resource problems and then correct them. This allows the person to see for themself how the memory works and how to fix common problems.

This is a case where people should read a physical book (or at a minimum chapter 7) if they want to improve their understanding:
