file security slow

[Guest John]

I have a folder on the 2003R2 file server that when I change folder security

settings takes a very long time. It seems much longer than other large

folders. Is there a tool that I should use in this type of situation that

can check for corruption...? Many files and folders in this folder have

very long names and possibly characters that should not be used.... Is

there a document that would give me ammunition to tell them to stop using

certain characters or exceeding some length?

No, it wouldn't be the naming convention. It may lie elsewhere. There is a

hug list of possibilities that can cause this from a multihomed DC,

incorrect DNS settings (such as using your ISP in your ip properties - which

causes numerous other issues as well), SMB signing issues, RSS settings in

the TCP stack on the server, network switch problems, to name a few.

 

Without config info, it will be difficult to diagnose. Are you the admin?

Can you provide an ipconfig /all of the DC? Does it happen with any server

or just the one?

 

Here is some reading for you to know what I mean.

Also consider disabling RSS (introduced with SP2)

2. RSS

3. TCPA

[Create DWORD values...]

EnableRSS = 0

EnableTCPA = 0

Re: file security slow

 

Hello John,

 

Thanks for your post here.

 

To verify the potential file system corruption, you can run "Chkdsk" that

will detect and repair varieties of problems such as cross-linked files and

directory errors. When the file system detects corruption, it logs an event

to the event log and you typically receive a message that prompts you to

run Chkdsk. Depending on the nature of the corruption, Chkdsk may or may

not be able to recover file data; however, Chkdsk returns the file system

to an internally consistent state.

 

As for max file path length and special characters that should not be used,

yes, Win32 programs are limited to a 256-character string size limit

because of the MAX_PATH variable. The file and folder name can be any

combination of letters (A-Z) and/or numbers (0-9), plus the following

special characters:

 

% Percent sign

' Apostrophe

` Opening single quotation mark

- Hyphen

@ At sign

{ Left brace

} Right brace

~ Tilde

! Exclamation point

# Number sign

( Opening parenthesis

) Closing parenthesis

& Ampersand

_ Underscore

^ Caret

 

Typically, files and folders with MAX_PATH length 256 exceeded or invalid

name are not allowed to create. From your description, the change of

security settings successes however it takes a very long time. This should

indicate folder structure is correct.

 

For this issue, I'd like to suggest you to shorten the folder name and

re-construct the folder structure to make it more plain. Then check how it

works.

Hope it helps.
