Yep, that looks like the same symptoms...

No, the file does not exist, neither before nor after attempting File ->
Save As -> PDF
What mode is the create?
In the detail field for the IRP_MJ_CREATE operation, I see:
Desired Access: Read Attributes, Synchronize
Disposition: Open
Options: Synchronous IO Non-Alert
Attributes: N
ShareMode: Read,W Write, Delete
AllocationSize: n/a

Your explanation makes sense... with my limited understanding of what is
going on under the hood, I figured that an operation with the name "CREATE"
meant it was trying to create something.

Hmm, OK. So maybe Acrobat Reader does not properly abstract file creation
functions? it depends on certain low-level operations specific to Lan
Manager?

Curiously this "directory" operation refers to the path of my target file:
\\AFS\ss2k.uci.edu\users\j\jnilsson\personal\tmp\jnilssonfile.pdf
In the "Save As -> PDF" dialog I chose my U: drive that gets automatically
created at login as defined in my Profile's "Home Folder" in Active
Directory. Since I'm not sure if that is equivalent to the SUBST command, I
just tried saving to another mapped drive created with SUBST. Same result.

That is true here as well. The "Filter" is "jnilssonfile.pdf" which of
course does not exist.

Very true... I do not see any IRP_MJ_CREATE operation that looks like it is
actually attempting to create a file. My suspicions are on Acrobat Reader
as well then. Acrobat Pro does work to save to AFS...
Thanks for the explanation!
