hi there - is this th right forum for network related questions?

we have set up a nice little LAN in our house - 5 PCS connected, with a further few to be added hopefully.
anyway At first all was fine, we have all shared our drives and have mapped eachothers drives/folders etc.
then something odd happened - my PC all of a sudden wont let people access it - everyone can see my folders Im sharing, but not open them - this is quite annoying if soeone is trying to access a cd in my drive or copy a file that im sharing.
the error message that is displyed is:

\\Freeb00ter\Mark's shared folder is not accessible.

not enough server space is available to process the command

where freeb00ter si the name of my PC- the one being tried to access
and "marks shared folder" is the name of the file i want to share and allow other people to access!
this is the error message they get when trying to access any of my fils....
i have not made any concious changes to my pc and wonder why all of a sudden people cant acces my stuff?
any idea people??
thankyou

What OS is on your computer?Try right-clicking the folders in question, selecting the Permissions tab & see what users are allowed & what they can do. It's possible to set up "look" only access to a folder, see it's contents but not explore further in.

Have you installed a firewall app perchance?

The other message is peculiar, but I've seen it before. If you're in Win2k/XP, read the error log. Or check the "Services Applet" and see if the "Server" starts up correctly. Some networking component may be screwed up. I advise you to try uninstalling & reinstalling "File and Printer Sharing" first, and if that doesn't work try some other Network components.

i have 2 firewalls - norton and zone alarm pro, both of whcih always have worked perfectly fine togther and have never caused problems on the LAN before.
i tried reinstaling file sharing componenet, but nothing much happened
looked at error log (i do have quite a few errors :-( ) but have no idea what most of them mean
the one relevant one i found was:

The server's configuration parameter "irpstacksize" is too small for the server to use a local device. Please increase the value of this parameter.

how do i increase this packet size?? as i presume this is why people cant access my pc when it says not enough space on server,, is is as simple as increasing the packet size and then all wil be ok? how do i do this??

thankyou

in services the server applet starts perfectly fine
by the way i use win 2k

Hmmm, that could imply that there's too many services running. Try increasing the value in the following reg key:

HKEY_LOCAL_MACHINE\SYSTEM\CURRENT_CONTROL_SET\SERV ICES\LanmanServer\Parameters

Change or add value: IRPStackSize REG_DWORD

The maximum value is 12 (C as hex), but 7 should do. It'll increase the size of the stack so that more servies can run concurrantly.

On one bootup, are there any/many other errors?

wow! i was a bit doubtful that it would work, but changing the number from one to seven seems to have done th trick!!! i dont believe it!!
thankyou so much, thats another of my "little problems off the list"
i hope these posts prove useful to other people another day too
while im online - can you recomend any reading/bokks/websites that can teach me more about the registry - its such a wide area i know, but anyhting that can teach me a few useful tips would be great
thanks again

Em, I can't claim the credit for this. I encountered this problem at work on a particularily troublesome PC some time age, and Googled for ages! I myself don't know a lot about the registry, but the little bits I've fiddled around with are usually to remove programs without their installer.

There are books on the subject, but it's hard to know a lot about the registry as it changes so much, every version of windows alters quite a bit. The the darker murkier depths are programmers only areas I'd say:/

I'll see if I can find anything funky,
GF

See whether your alert services is stopped in services .that may be the problem
