can't open image sequences on network

i'm on a network and i'm trying to open an image sequence with Adobe After
Effects and Autodesk 3D Studio Max but they don't recognize the numbered file
lists as sequences they only recognize them as individual files
this only happens to files on the network, if i copy the image sequence to
my computer locally the image sequences open fine, both applications
recognize the files as sequences

has this ever happened to anyone, and do you know how to fix it?

i'm almost positive this is a Windows networking problem and not an
application problem with After Effects or 3ds Max because my computer is the
only computer on the network that is having this problem, the other computers
on our network can open the image sequences on the network fine
so i think maybe this computer wasn't set up to the network correctly or
maybe there are settings i have to change


here is an example of the problem:
the folder on the network i'm working off of is mapped as the Z: drive
lets say the image sequence is located in the Z:\images folder
and say the sequence is 48 frames, the start frame is test0001.tga, the end
frame is test0048.tga
if i try to import a file in After Effects (File | Import | File...) and
navigate to the Z:\images folder and click on the first file (test0001.tga),
or any file, in the image sequence at the bottom of the Open Dialog the image
sequence options are disabled or grayed out
at the bottom of the Open Dialog it should say:
Import As: Footage
[x] Targa Sequence (these are check boxes)
[ ] Force alphabetical order

but for me it says:
Import As: Footage
[ ] Sequence not available
[ ] Force alphabetical order
and everything is grayed out/disabled so i can't select how to import the
footage as or check the sequence box, so i never get a chance to import the
files as a sequence, the files are recognized only as single files not part
of a numbered list

if i copy the folder to my computer locally like for example to: C:\images
and i try to import the file from there everything is fine, the Import As:
Footage, and Targa Sequence options are enabled and the image sequence loads
fine
also if the folder is saved on to a removable harddrive like an external HD
or jump drive it also works fine, the only problems happen if the files are
on the network
and it only happens to my computer, the other computers on the network can
load image sequences off the network fine

so is there a proper way to map the network drive or set up a network on my
computer that might solve this problem? or are there settings i can change
for the network that would fix the problem?

to map the network here is what i did (for the example i'll use WKserv as
the server, and Project as the volume on the server):
1. Start | My Computer
2. clicked folders icon and navigated to: My Network Places | Entire Network
| Microsoft Windows Network | Workgroup | WKserv | Project
3. entered my log in information and saved it
4. right clicked on My Network Places and clicked Map Network Drive
5. set the Drive letter to Z:
6. set the Folder to: \\WKserv\Project
7. checked Reconnect at logon, and hit Finish


Any help would be appreciated, i've never had this problem before that's why
it's so strange
right now to work around it i'm just copying my files from the network to a
local folder and working off that but it's time consuming transferring files
and just annoying, i'd rather just fix the problem
thanks,
