VFP 9.0 can't see mapped network drive

[Dan Musicant]

I have 4 PCs running Windows, 3 of them running XP, the other running
Windows 7 64 bit Ultimate. I have my data on an XP machine and the drive
with the data is mapped on the other machines as T:

VFP 9.0 has no trouble seeing the data from the XP machines but VFP 9.0
on the Windows 7 machine does not see the drive although it's clearly
there in Windows Explorer on the machine. What's at play here?

Probably some UAC-related something or other. You should probably ask
in a Windows NG because it doesn't have anything to do with VFP.

Having said that, mixed Windows versions in a peer-to-peer LAN has
never been a recipe for success, nor has sharing VFP data on a
peer-to-peer LAN.

YMMV

I'm pretty much depending on peer-to-peer data sharing working for this.
It's working pretty well at the moment, with occasional hiccups.
Hopefully, I can reduce the problems over time. I'm assuming I can. The
data did show up on the Windows 7 machine finally, don't know what the
issue was.

I'm not sure this is actually peer-to-peer. Well, maybe. I have a
wireless router, the data bearing machine and my desktop are connected
by ethernet to the router. The data is on a shared drive and all the
machines are in the WORKGROUP. I map the drive from the other machines.
It's the only way I can centralize my data in such a way that it doesn't
drive me nuts. I've been planning this for literally years. I did it for
a while from a laptop and it worked out, with a lot of hiccups. That
laptop died last summer. I was going to build a low power server machine
to connect by ethernet to my router but got an extra laptop and decided
to try using it for a low power server. I'm actually getting better
results now, probably because the data serving laptop is connected by
CAT5 to the router rather than the way I had it set up before, which was
wirelessly. Until this latest incarnation of an actual server machine, I
was doing sneaker net (flash drive or an external HD, on occasion) +
emails. Nasty stuff, and I've endured it since last summer! I'm even
planning on having all my email/NG data on the server machine, which is
somewhat more risky (in my experience), so as always, I plan on having
backups in case of data loss or corruption. And, of course, HDs are
prone to failure, so backups are always a good idea.

It's really quite a simple determination. Wiring and routers don't have
a darned thing to do with it.

* Windows XP is *NOT* a server operating system
* Windows 7 is *NOT* a server operating system

You are sharing data on a peer-to-peer network. This has never been
considered a best practice. Your "hiccups" are likely to continue and
the only advisable solution is to plunk an actual server running an
actual server operating system into the mix. <shrug>

How about a low power server running Windows Home Server? That's
presumably Windows Server 2008 adapted somewhat for home use. It's about
$100. Gets great reviews. I didn't do it for a couple of reasons right
now. Firstly, XP's already on the machine and secondly I saw it said
that WHS is really not supported on laptops, and the machine is a
laptop.

I'm not getting hiccups at the moment, but it's early, I've only had
this setup running a few days. However, it's looking way more stable
than what I had when the server laptop was connected wirelessly to the
router.

Boy you just insist on using as many data corrupting techniques as
possible, eh? <g>

"laptop server" and "wireless" are concepts that have absolutely no
place in an application where the single most important requirement is
an unflinchingly reliable persistent connection to the server.

Might work just fine for a while. Should we take bets whether it'll
fail at exactly the worst possible (and MOST expensive) time for the
business? Murphy will see to it.

I have no experience with WHS beyond backups, where it is an excellent
option. I won't run a business on a product intended for home use.

Well, I'm not running a business with this network. It's basically for
my own information management system for my personal info (I have a
lot!). In any case, I don't want to lose my data, but I've managed OK
over a number of years without significant data loss.

I did some research into whether or not I could actually run XP on this
laptop rather than Windows 7, and people in the know said the answer was
"yes." The machine is actually licensed for Vista Business 32 bit, and
running XP is said to be an option in the EULA. I put Windows 7 64bit
Ultimate on it simply because I have a copy and the machine supports it.
If I appear to be having vexing problems that downgrading to XP will
solvem I may opt to put XP on this machine. However, I figure it IS a
good idea for me to get into later OSs, so I'll try to work through the
issues.
