Is it possible to access data from a Solaris Server on Windows XP machine?

Absolutely. You have a number of possibilities, SAMBA and Solaris SMB
probably being the best choices. See section 9.14 here for setup info:
http://www.sun.drydog.com/faq/9.html

As for dealing with authentication, see here:
http://wikis.sun.com/display/SecureGlobalDesktop/HOWTO+Use+Active
+Directory+as+a+Solaris+Authentication+Source

If
so could you provide tools or strategies to accomplish this. I've heard of
SAMBA but would prefer some detail on how this works, i.e a share on the
Solaris box would have to be a SAMBA share would it not?

Correct.

 Is it possible to
access data on a solaris server from a windows machine in the same active
directory domain, but without any specialist software?

Not really. The systems default to different communication protocols.
You have to load something that will permit them to speak a common
protocol.

I have a copy of the /etc/shadow/ file from the Solaris Server which
contains the encrypted passwords but I cannot find any Windows based
crackers that will crack these passwords.

First, what hash method are you using? I have not mucked with Solaris in
a while, but the last I checked it still defaulted to the insecure
crypt() hash, which limits passwords to 8 characters. MD5 and Blowfish
are also options, but you have to enable them. Check
your /etc/security/crypt.conf file to be sure.

As for crackers, if you are using Crypt or MD5 pretty much anything will
work (John the Ripper, Cain & Able, Crack, etc. etc. etc. etc.).

Just out of curiosity, you did unshadow the file before trying to crack
it, correct? If not that would give you trouble as well.

 I also dont know what client
software would be required to access data on the Server from a Windows
machine even if I do decrypt some weak passwords?

With a proper setup you should not need to crack any passwords. Just
sync the Solaris box to AD as described in the link I gave you above.

 Did see some mention of
Putty but am unfamiliar with this or SAMBA.

Putty is a Telnet/SSH client. You can use it to access either service if
it is running on the Solaris box.

 I also assume that any "open
file shares" on the Solaris box wont be mappable or reachable to a windows
machine, as is the case on win2k and windows 2003 servers, when all you need
is my network places and hope some of the shares hav been given the deadly
"everyone acl" in NTFS?

If the shares are setup properly, they should be mappable. A good SAMBA
setup looks like a regular Windows server to the typical end user.

 I appreciate Solaris uses a totally different file
system to NTFS but I assume you can share directories with anyone on the
network if desired? Any tips on accessing data on this Server from Windows
much appreciated.

SAMBA (or Solaris SMB) will let you define the level of access you want
to permit. Again, the links above will give you more info.

Out of interest, what are the mailing lists views on Security of a Solaris
Server if every user on the internal network only have windows machines?

The Windows systems are beside the point. The security of the Solaris
system will depend on who locked it down and how good of a job they did.
With that said, my experience has been that when you find a single UNIX
type system on a network, it was typically setup by the Windows Admin
who may not be 100% clueful when it comes to UNIX type security.

Even if there is a weak password or open file share on the Solaris Server,
without specialist software is it fair to say the windows users still
wouldnt be able to get hold of data on the Server, or is that a very naive
view on things?

I'm reminded of Adrian Lamo, who came to fame from being able to break
into just about anything using nothing more than a public access Web
browsers. ;-)

If the person knows what they are doing, the platform mix is a
non-issue. You can go quite far with Netcat and some skills.

HTH,
