Help - lost existing network, access denied - after upgrading to SP2
Hi all,
I have a problem with my existing network at home - I have had a fully functional network at home with 2 desktops and 2 wireless laptops sharing an internet connection via Linksys router on WinXP. The problems occured after I upgraded one of my laptops and one of my desktops to SP2. The upgrade went flawlessly. However, when I click on the network neighbourhood and select one of my four computers - I get an dialog; "Computer Name is not accessible... you may not have permissions... contact network administrator... Access denied" I am logged in as the administrator. What had changed? I still see all my computers in the neighbourhood. Simple File Sharing is set on I have shared certain directories and drives before I upgraded to SP2 I've checked the firewall - and filesharing exception is checked. I've got internet sharing on all computers I've pinged each computer and I get a return I've confirmed that Computer Browser in Services has started and is automatic I've tried TCP/IP advanced from standard to NetBios over TCP/IP I've tried the network wizard disk on all computers I've renamed my workgroup to HOME and each computer to ONE, TWO, THREE, FOUR None of these seem to work to allow me access so far. Funny occassionally, I see a shared documents folder in my Network Places, and I can copy to it - but I can open the computers themselves. Is there something new in SP2 that I need to set permissions? I haven't set any passwords for anything - its only my wife and I at home, so we each just log on with our names without passwords and WindowsXP just loads onto the desktop without asking (which is how we prefer it). I actually re-installed WinXP (SP2 slipstreamed) on my desktop - thinking something got mucked up in the upgrade - but still no go. So far I have very little back on my desktop - its still pretty much a bare clean install - just updated from MS, MS Office and Norton SystemWorks 2005 - but NO Internet Security. Help, any suggestions would be helpful. Wm |

Hi William,
Certain features of file and printer sharing have been modified in SP2 to enhance security.

Thanks,
But could it be anything else? How does one give permissions? I'm pretty sure its not a hardware problem - my NC is working - I have stable internet connections on all computers.

Thanks Anando,
But unfortunately, the MS article wasn't of much help. As I mentioned before, my Windows firewall has the proper file sharing exceptions enabled. I don't use passwords (and would prefer not to - unless SP2 absolutely requires them now for networking) so the rest of the article didn't apply to me and I do have all my updates in order. Anything else - its not a hardware problem, its some software permissions. With my laptop at work, I can get onto other people's shared folder and computer - but they can't get onto mine. I show up in the workgroups, but when they click on me, they get the same "access denied" dialog I get at home. So it must be me! "Anando [MS-MVP]" wrote in message ...

Hi Anon,
Unfortunately, after much reading, the articles were not of much help. The articles that relate to hardware diagnosis doesn't relate to me, nor the wireless networking - its not the hardware, its the software security portion. All the pings confirm I have a network that talks to each other (which was perfectly fine before I installed SP2!) As I have mentioned above in my original posting, I have tried a lot of these solutions already - with the exception of repairing my IPSTACK and WINSOCK (which I don't think could be corrupted since I did a clean install of WinXP SP2 on the desktop). Additionally I do know how to configure file sharing - I've done it for years until the SP2 upgrade. I just don't get what I'm missing - arghh! I'm at wits end now - wasted so much time trying just to get back what I had! The upgrade to SP2 was the worst decision I've made in a long time - nothing was wrong before! If it ain't broke... don't fix it. But know I can't really go back unless I re-install everything. How do I set permissions to allow each other to log onto the computers?

What are the os's of each workstation?
FAT's can't access user accounts on NTFS (WinXP) boxes. Win9x loggon to XP boxes as a "guest" and can access the "All User" account only. I just had a similar issue resolved. With this comment.

In article , "mgm"
wrote: What are the os's of each workstation? FAT's can't access user accounts on NTFS (WinXP) boxes. Yes, they can. A Win9x computer can't access an NTFS partition on its own local disk, but that doesn't apply to accessing a shared disk over a network. All versions of Windows can access shared disks and folders on all versions of Windows. It makes no difference what the disk format is on any computer. For example, an XP computer with an NTFS can read the data on its disk and send it, over the network, to a Win9x computer that has a FAT disk. Win9x loggon to XP boxes as a "guest" and can access the "All User" account only. I just had a similar issue resolved. With this comment. "XP Home does not allow sharing of the My Documents or Program Files Here's the full story: When XP Home is installed on an NTFS disk partition, it blocks networked access to the Program Files and Windows folders and to individual users' folders (but not the "All Users" folder) within Documents and Settings. I think that's a bad design, but that's how Microsoft did it. You can share subfolders within those folders, e.G. you can share "C:\Program Files\Outlook Express" or "C:\Documents and Settings\Username\Desktop" and access that folder from another computer on the network. In Windows XP Professional, you can disable simple file sharing, which removes those sharing restrictions. -- Best Wishes, Steve Winograd, MS-MVP (Windows Networking) Please post any reply as a follow-up message in the news group for everyone to see.

Solution found,
It wasn't the upgrade to SP2 afterall, it was the immediate installation of Sunbelt's CounterSpy right after the SP2 install. There are security optimizations which the anti-spyware program performs - one of which closes a potential hole of "Restrict Anonymous Access". That registry entry has been subsequently restored - and now I have access to my other computers. I hope this helps others. Thanks. "William Cheng @work" wrote in message ...

A Solution!
It wasn't WinXP SP2 after all, it was Sunbelt's CounterSpy. In its efforts to tighten security, it changed a registry setting so that it no longer allowed anonymous logon. Unfortunately, the program cannot reverse its setting and un-installing it does not reverse this setting either. Fortunately after e-mailing Sunbelt's support, they were able to create a REG file for me to patch my registry - which solved it! Thanks to all who helped - and I hope this solution may help those in the future. "William Cheng @work" wrote in message ...
