Dreamweaver CS4 reports 'Access denied' on file save?

Hi TCCWebservices,

How is Check-In/Check-Out defined for this site?

OS Windows XP Pro
Dreamweaver CS4
Network connection: LAN/Novell Netware client
- I connect to site using My Network Places.  I can get to the site just fine through Windows Explorer, see the files, and I can even see the remote site in Dreamweaver.

Site set up: Local/LAN connection.  This same config worked fine a week ago...
  Back story: a week ago, our network technicians changed my authentication method from a windows workstation to a domain authentication.  Now, my DW is wigging and they're
  "not software support." Gotta' love the techs!

Answers to site configuration questions...
- DW Testing server: not being used
- Check-in is "enable contribute compatibility"

I think I'm going to uninstall/reinstall dreamweaver.  

i'd wait a sec on uninstall/reinstall; Don't have solution yet but you should try this first: Reset DW prefs, after you launch the program (i know launch is causing errors) immediately press and HOLD the Ctrl+Alt+Shift keys until you see a dialog to delete the prefs and click Yes/OK.
HTH

also, if you connect to the site using My Network Places then there should be no "Access to C:\.....file.php was denied message since My Network isn't about C:

Try disabling check-in/check-out and contribute compatibility and see if you can save files.  I agree with GlennHarris that uninstall/reinstall probably isn't needed here.

Everything is cleared up now.  I followed your suggestions, Glenn and Jason, and I also turned off the site cache in the site config.  DW starts in a few seconds now and I can download/save/put without it prompting me to overwrite my local copies.

Here we go again, with a slightly different twist.  Now, when opening files, I get "Access to ...\_notes\dwsync.xml was denied."  Then the file opens.  I can modify, but on save I get the "Access denied to c:\...file.php" message I got earlier in this thread.  Here's the clincher: I do not have synchronization active on any of my sites, although it was at one time and I deactivated it.  I understand that dwsync.xml has to do with synchronization.  

Something else I'm putting out there, because it's totally off-the-wall but may hold some nugget of causality... why is it doing this today and yesterday it was fine?  Yesterday I was humming along, getting, putting, no problem.  Locked my workstation, went home, came back this morning, unlocked it, and Bam! can't get dwsync.xml.  At night, the servers do disconnect me from all my network drives but on login I get reconnected.  I tested this several times, and I am definitely connected to my network drives.  

Oh, it's also prompting me to "overwrite local copy of file.php?" whenever I open something.

More goodies.  Here is a full sequence of errors when I open a file:

double-click to Open file...
Error box:  "Overwrite local?"   (I click Yes)
Error box:  "Access to c:\folder\index.php.lck is denied"  (I click ok)
{File opens}
Background file activity box:  "\\xxx.xxx.xxx.xxx\data\web\htdocs\index.php  An error occurred.  The handle is invalid."
{I modify something, try to save by clicking "save" button}
Error box: "Access to c:\folder\index.php is denied"
{File not saved.}
-------------------

If I exit DW and copy-paste to notepad, I can save files.  This makes it very confusing and is an EXTREMELY cumbersome workflow (DW-notepad-notepad-DW).  

Thanks for your help on this most annoying problem.

You should always a) exit indesign and save your documents; b) restart the computer daily.

Hi Glenn and Jason,
I am running Windows XP Pro.  *VERY* interesting point about the permissions, Jason!!   Recall that our network technicians changed my authentication method from a windows workstation to a domain authentication; that may have had something to do with disappearing permissions because of heightened security as you point out.  That sounds like the single-most promising advice yet...  the next time this acts up on me, I'm moving my sites to Documents and Settings.

I say "next time" because when I brought my machine up from a clean boot this morning, and the problem "cleared."  I can open files without it asking to overwrite existing ones, modify files, save, put, and check-in just fine.  It did this once before, too, then reverted to its old behaviors so I have reason to believe that it will begin its shenanigans again soon.  I'll keep you posted.  Thanks for the assistance.

XP shouldn't care about writing to the C:\ so that narrows it down to three possibilities:

1) Your network policy is interfering
2) Your anti-virus software is treating the write as "virus-like" activity
3) We're totally wrong and it's something else entirely

Jason, you were right on:  it was the rights/security policy.  Because I created the affected folders on my C: drive using my old Windows user account, when they switched my Windows login account the new username, it did not by default have rights to modify files in the folders created with the old account.  The DW error was because it legitimately didn't have rights to edit files in my local website folder.  The reason I was able to write some things and not others was because the new user account *did* have write permission to some of the subfolders inside the main folder.  The PC techs came this morning and "helped" me with this (it was more like... "hi, guys, can we try this...").  LOL.  Thanks for your help, Jason!

It was, in fact, a permission issue: instead of moving the affected folders, my PC's admins granted my Windows account full rights to them.
